HP's "Memory Spot" research team has developed a memory device, based on CMOS (define) integrated circuit design, that includes a built-in antenna and 10 Mbits/sec. data transfer rate, comparable to Wi-Fi (define) speeds.
Low Power? How about none? Just like an RFID (define) chip, the Memory Spot is completely self-contained with no need for a battery or external electronics. HP said 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.
Analyst Tim Bajarin has seen the prototypes and is very excited about its potential a few years down the road.
"It's a fascinating technology, but remember this is only a technology announcement coming out of HP Labs," Bajarin, president of Creative Strategies, told internetnews.com. "For it to become a commercial product, HP's got to line up all kinds of partners to make the chips, make the readers, and set up any licensing. It's going to be a two- to five-year process for this to become ubiquitous."
