Cambridge University researchers have developed an inexpensive write once, read many (WORM) memory device that uses much less power than previous devices. The ultralow-power WORM device can be used in any organic electronic circuit in which the operation power is low.

The researchers say their device is designed for use in disposable radio-frequency identification tags, which need inexpensive memory devices that require very low current consumption.
