BBC NEWS | Technology | Tiny wireless memory chip debuts A new 2-4mm square chip, developed by the Memory Spot research team at HP, can hold up to 512 kilobytes of data,that can store 100 pages of text and swaps data via wireless.

Data can be moved in and out of the chip at speeds of up to 10 megabits per second – far faster than is possible with other short-range radio systems such as Bluetooth or radio Frequency ID tags.

All the components to make the chip, including modem, antenna, microprocessor and memory, can be fabricated as a single unit helping to keep unit costs low. HP speculated that once in production the devices could cost as little as one dollar each. No battery is needed because devices reading data from the chip will provide power by induction.
