HPHP Wireless CMOS memory chip : HP today announced that its researchers have developed a miniature wireless data chip that could provide broad access to digital content in the physical world. Memory capacity and data access speed, the tiny chip could be stuck on or embedded in almost any object and make available information and content now found mostly on electronic devices or the Internet. Some of the potential applications include storing medical records on a hospital patient's wristband; providing audio-visual supplements to postcards and photos; helping fight counterfeiting in the pharmaceutical industry; adding security to identity cards and passports; and supplying additional information for printed documents.
HP Wireless CMOS memory chipHP CMOS chip - Antenna
The experimental chip, developed by the "Memory Spot" research team at HP Labs, is a memory device based on CMOS (a widely used, low-power integrated circuit design) and about the size of a grain of rice or smaller (2 mm to 4 mm square), with a built-in antenna. The chips could be embedded in a sheet of paper or stuck to any surface, and could eventually be available in a booklet as self-adhesive dots. "The Memory Spot chip frees digital content from the electronic world of the PC and the Internet and arranges it all around us in our physical world," said Ed McDonnell, Memory Spot project manager, HP Labs.

HP Wireless memory chip - Data transfer
The chip has a 10 megabits-per-second data transfer rate 10 times faster than Bluetooth wireless technology and comparable to Wi-Fi speeds effectively giving users instant retrieval of information in audio, video, photo or document form. With a storage capacity ranging from 256 kilobits to 4 megabits in working prototypes, it could store a very short video clip, several images or dozens of pages of text. Future versions could have larger capacities.

HP Wireless memory spot chip - Information
Information can be accessed by a read-write device that could be incorporated into a cell phone, PDA, camera, printer or other implement. To access information, the read-write device is positioned closely over the chip, which is then powered so that the stored data is transferred instantly to the display of the phone, camera or PDA or printed out by the printer. Users could also add information to the chip using the various devices. "We are actively exploring a range of exciting new applications for Memory Spot chips and believe the technology could have a significant impact on our consumer businesses, from printing to imaging, as well as providing solutions in a number of markets," said Howard Taub, HP vice president and associate director, HP Labs.

HP Wireless CMOS memory chip - Power
The chip incorporates a built-in antenna and is completely self-contained, with no need for a battery or external electronics. It receives power through inductive coupling from a special read-write device, which can then extract content from the memory on the chip. Inductive coupling is the transfer of energy from one circuit component to another through a shared electromagnetic field. A change in current flow through one device induces current flow in the other device.

HP Wireless CMOS memory chip - Consumers
- Medical records: Embed a Memory Spot chip into a hospital patient's wrist band
- Audio photo: Attach a chip to the prints of photographs and add sound
- Digital postcards: Send a postcard containing digital pictures, plus sounds
- Perfect photocopies: Just read the perfect digital version into the photocopier
- Security passes: Add a chip to an identity card or security pass for the best of both worlds
- Anti-counterfeit : Chips can contain information about the quality of pharmaceuticals
