DailyTech – Researchers Create New Memory from Graphene .

Researchers have devised a way to build memory from graphene

Storage in today’s computers is based on rotating magnetic platters or flash memory. Both of these mediums work well, provide large amounts of storage and have been around for a while now. Some scientists don’t believe that flash is the future for storage in computers and electronic devices. In fact, the future of storage could be based on something kids use every day at school — pencil lead or graphite.

A team of researchers at Rice University has found a method of creating a new type of memory from a strip of graphite only 10 atoms thick. Graphite is the basic element in the new type of memory. The scientists describe in a paper published in the online journalNature Materials a storage device that utilizes the conducting properties of graphene. A large clump of graphene is better known as graphite, something school kids doodle with everyday.

Rice professor James Tour says that graphene memory would increase the amount of storage in a two-dimensional array by about five times. He says that this massive improvement is due to the individual bits being able to be made smaller than 10 nanometers. By comparison, circuitry in your average flash memory chip today is 45nm. Another big benefit of graphene memory is that switches can be controlled by two terminals rather than the three terminals used in flash memory today.
