I Don’t Want to Work Hard to Understand My Refrigerator

Apps on Your Fridge by Samsung http://bit.ly/nZXCPo

According to the Zpryme Smart Grid: Smart Appliance Insights report, “from 2011 to 2015, the global household smart appliance market is projected to grow from $3.06 billion to $15.12 billion, respectively with a compound annual growth rate (CAGR) from 2011 to 2015 is projected to be 49.0 percent.” With a large market growing larger that fast, companies take immediate notice.  That was definitely evident by the myriad of announcements of smart appliances at the recent International Consumer Electronics Show in Las Vegas.

There is Smart and There is SMART

As discussed in a recent New York Times article “Not Quite Smart Enough”, smart appliances have a ways to go before they can be really “smart appliances”.  Andrew Martin warned us not to expect a Jetsons lifestyle anytime soon.  Well, let’s look at the types of smartness in today’s appliances and see if he is right.  Typically, you find smartness in four areas:

  • Interaction with other appliances and the smart grid
  • Interaction with owner’s smartphone as a remote management solution
  • A centralized hub in the kitchen to information from the Internet
  • An ability to track interesting information, such as food in the refrigerator

The low-hanging fruit is the first three items while the last one is the most difficult.  Integration into a smart meter (and consequently the smart grid) is probably the easiest and most non-invasive.  With additional information about energy consumption devices, you and your utility can better manage your overall energy consumption and manage the load.

The next level of smartness is to allow remote monitoring and access through your smartphone or tablet device. Your washer can tell you when your wash cycle is done and you can easily stop and start the dryer when leaving and returning to your home. No guarantees on wrinkle-less clothes though.  Now, if it could only separate the whites from the colors!

The smart refrigerator promises to be a hub of information from the Internet within the kitchen.  Internet radio solutions like Pandora and Spotify can be streamed and recipes, photos and weather can be displayed. The key question is how easy will it be to manage this additional source of information; will consumers go to their refrigerator as opposed to their tablet or smartphone?

The last level of smartness is the most difficult, but the killer application for smart appliances.  Smart appliances hold the possibility of being information databases about their primary activity.  For example, refrigerators would track the food inside.  Imagine being able to cross-reference a recipe with the contents of your refrigerator while standing in the supermarket.  Or by knowing the upcoming expiration dates, forever ending the science experiments that you are afraid to clean up that exist in the deep recesses of your refrigerator!

Unfortunately, today the information database approach requires significant human interaction – scanning the receipt or the individual bar codes. For someone with specific dietary needs, it may be a good solution, but for most people, we don’t want to work hard to understand our refrigerator. More automated solutions are needed.

The Value Needs to Exceed the Cost

Much of the discussion of smart appliances has been about the technology integration; however, the adoption will explode when the consumer benefit exceeds the cost, including acquisition cost, ease of interactivity, and reduced privacy risks.

Value-added software will be critical for consumers to pay an additional premium.  The increasing complexity of the software will drive more sophisticated memory requirements leading to more use of NOR flash at higher densities. The communications with the smart grid will drive more requirements for performance.

With your smart meter talking directly with your refrigerator, air-conditioning and washer/dryer, valuable data is leaving your home. This information is great to help manage their energy usage, but brings a host of privacy and security issues, particularly around personal information.  For example, will that gallon of Ben & Jerry’s Chunky Monkey ice cream eaten in the span of last week come back to bite you with higher health insurance payments?  Or will you simply be overwhelmed with coupons from Haagen Dazs trying to muscle in on the action?

Protecting your personal data will require Flash Memory that cannot be tampered with. NOR flash often contains the software that secures access to the content as well as the operating system and other middleware. Designers use the security features within the NOR flash such as permanent lockable region to protect against write or erase access by hackers and a One Time Programmable (OTP) region for sensitive data such as encryption keys and unique IDs.

Someday We Will Have the Jetsons

Unlike Andrew Martin’s assessment in the New York Times article referenced above, smart appliances do indeed have huge potential to change our lives for the better.  The technology exists or will shortly exist to solve many of the remaining challenges to smart appliance adoption and when the value outweighs the costs, adoption will soar.  Now, when can I get “Rosie the Robot” so she can make my bed in the morning?

7 Top Phrases that Hit the Jackpot at CES 2012

Nothing new.  That was the conventional wisdom about CES 2012 in Las Vegas.  Well, after spending two days last week at the show, I think the conventional wisdom is wrong.  There are many new and cool electronic products at the show and they all point to exciting times for Spansion and our customers.  Why?

Set Top Box: The Center of Your Viewing World

The Set Top Box (STB) is the center of your viewing world delivering premium content and services to you through a variety of broadcasting mediums (Satellite, Cable, Terrestrial, IP).   Consumers are demanding media-rich home entertainment requiring STB evolution to include more advanced features and services and driving an architecture for faster performance, scalability and security.

More than just ABC/CBS/NBC with a Remote

In a Digital TV (DTV) system, a Set Top Box receives, filters and processes all the content and services accessed by the TV viewer.  Evolving from a simple Standard Definition device that offered a basic Electronic Program Guide (EPG) information and access to a limited set of services and content, newer STBs support:

  • High definition channels
  • Multi-tuner capabilities (enabling simultaneous viewing and recording)
  • IPTV in addition to broadcast TV
  • Pay per view/video on demand services
  • Internet interactivity

STBs are also increasingly assuming the functions of home gateway or home server devices that can store as well as distribute content to many TVs, PCs and portable devices throughout different rooms inside the home.

Give me Access to that Content

Increasingly, consumers want access to the content on their terms: on-demand and on this device. While everyone would love to get the content for free, normally access comes at a cost.  Consequently, both the consumer and the pay-TV operator must rely on the STB to be the platform for secure transactions and content protection. 

For consumers wanting privacy and content providers wanting to protect their revenue stream, security within the STB is critical and falls in two areas:

  • Conditional access systems (CAS) – Securing the content as it is delivered from the operator to the STB by ensuring that consumers can only play content to which they are entitled.   The overall user entitlement process is handled by the conditional access kernel (CAK) and a conditional access module – often contained in a SmartCard- inside the STB.
  • DRM (digital rights management) – Protecting the content as it is stored in the STB or shared with other devices and users through a home network such as WiFi.  The DRM technology is typically handled by the middleware software and therefore needs to be secured from hacking as well.

NOR flash provides a key role

NOR Flash contains the boot code, CA kernel, operating system kernel, device drivers, middleware and the EPG.   The boot code and the operating system code require high random read performance and data retention making NOR flash the ideal non-volatile memory solution, directly impact the viewing experience by providing a near “Instant On” experience so they can access their desired programs quickly.  Unlike other consumer electronic systems, TV operators actively manage the STB once it has been supplied to the consumer.  Higher-density NOR flash memory can be provisioned for future software additions or upgrades.

In providing security in the STB, NOR Flash is particularly important. To secure the CA kernel, the OS and the middleware codes, the NOR flash contains security features such as permanent lockable region to protect against write or erase access by hackers and pirates and a One Time Programmable (OTP) region for sensitive data such as encryption keys and unique IDs.

Spansion’s 65nm NOR products Family offer features that address the STB’s performance, scalability, performance and total cost of ownership.   The Spansion® GL-S family is the latest generation of Parallel NOR products that have been well established in the STB market for many years, and Spansion Serial NOR products have ramped up quickly in STB applications since 2010 because of its reduced pin count which simplifies board layout and results in lower system costs and reduces the form factor of many embedded designs.  The latest generation of Serial flash, Spansion FL-S family, brings high performance benefits to simplified memory interface.

Gaming Graphics Get More Flashy

About 5 months ago, a very interesting point-and-click adventure game called Superbrothers: Sword & Sworcery EP was released for the Apple iPad.  Was it because it has outstanding, immersive gameplay? No, it was released with incredible 8-bit visuals, challenging puzzles and an awesome soundtrack. Indeed, it was quite different than the predominate trend in gaming: more realistic and more immersive interactive graphics.

From Casual Handheld to Professional Simulations

The push for more action and realism is driving higher requirements for performance and capacity in NOR memory within embedded devices from simple handheld gaming devices to high-end professional games and simulations.  One can say that “the flashiness of the game is driving the flashiness in the system” – all pun intended!

Three key memory characteristics are critical to graphics processing in these systems: data throughput, initial response times and total storage capacity.  Unfortunately, balancing these tradeoffs against one another is a tricky proposition. Without superior data throughput, the gaming experience would be lost as jittery graphics would destroy the illusion; yet, fast initial response times are needed to handle fast random reads due to the interactivity of the gameplay. Traditionally, NOR Flash has handled these requirements quite well. High performance is enabled through burst mode and simultaneous read/write operations for fast boot and quick application loading.

The drive for greater, more comprehensive realism has also increased capacity requirements. When one thinks of higher capacity requirements and flash memory, one immediately thinks of solid-state disks (SSDs). Undoubtedly, SSDs are driving the limit for higher capacity with NAND flash devices and will continue for the foreseeable future.  NAND Flash (64Gbit) clearly can scale to larger densities than NOR flash (now 4Gbit), but with the cost of a significant impact on initial access times due to NAND’s parallel configuration of multiplexed address and data buses. However, the push for higher capacity combined with superior performance is creating demand for another growth segment in the market, high-density NOR.

Spansion recently introduced the industry’s first 4Gb NOR Flash at 65nm. Built for speed, the chip has fast random read for interactive operation, fast programming for time efficient software development, and very high reliability for long-term operation. With these types of advancements, dual requirements of performance and capacity are best delivered by high-density NOR; particularly for 2D and 3D graphics, animation and video used in games, learning devices and automotive infotainment and instrumentation clusters.
