HP Announces Tiny Memory Chip

Hewlett-Packard researchers have developed a memory chip with wireless 
networking capabilities that is roughly the same size as a grain of rice, the 
company
said Monday.

Prototypes of the Memory Spot chip developed by HP Labs contain 256 kilobits to 
4 megabits of memory and can transfer data wirelessly at speeds up to 10
megabits per second. (There are eight bits in a byte.) This amount of storage 
allows the chips to hold a short video clip, digital pictures, or "dozens
of pages" of text, HP said, adding that the chips do not require a battery.

Memory Spot chips get their power using a technique called inductive coupling, 
which allows power to be transferred from one component to another through
a shared electromagnetic field. In the case of Memory Spot, this power is 
supplied by the device that is used to read and write data on the chip.

Data stored on Memory Spot chips could be accessed using a variety of devices, 
such as specially equipped cell phones or PDAs, making them suitable for
a range of applications, such as adhesive attachments applied to a paper 
document or printed photograph, HP said.

HP is considering different applications for the chip, but has yet to say when 
the chips will be available.

The Memory Spot is similar to
RFID (radio frequency ID) chips ,
which are designed to store information that can be read wirelessly. However, 
there are several important differences. One such difference is range. 
Information
on RFID chips can be read over relatively large distances while HP said Memory 
Spot readers must be "positioned closely" to access the data stored on the
chip.
