Ultralow-power memory uses orders of magnitude less power than other devices

As RFID tags are becoming more widespread for tracking and identifying almost anything, researchers are continuing to develop cheap, ultralow-power memory devices for these applications. In a recent study, scientists from Cambridge have taken another step forward in this area by developing a write-once-read-many-times (WORM) memory device that requires just a fraction of the power needed by previous devices. In principle, the low-power memory can be used in any organic electronic circuit where the operation power is low.
