Plastic memory gets tough

  November 10/17, 2008
Cook up a durable plastic that can be switched between high and low electrical conductivity and you have the makings of very inexpensive computer memory that stores data with the power off.

Liquid polyimide can be made into memory cells simply and inexpensively. Prototype memory devices made from the material stand up to high temperatures and harsh conditions better and require less power than previous plastic memory devices.

The material can be layered to make high-capacity three-dimensional memory chips.
