Data that lasts—modification of ferroelectric transistor structure improves memory retention

By Lisa McDonald / March 10, 2020

Ferroelectric field-effect transistors are nonvolatile memory devices that nondestructively read stored data. However, data retention times in these devices are short. Purdue University researchers suggest a modification to conventional Fe-FET structure could overcome this obstacle.
