Recent Process of Flexible Transistor‐Structured Memory

Abstract

Flexible transistor‐structured memory (FTSM) has attracted great attention for its important role in flexible electronics. For nonvolatile information storage, FTSMs with floating‐gate, charge‐trap, and ferroelectric mechanisms have been developed. By introducing an optical sensory module, FTSM can be operated by optical inputs to function as an optical memory transistor. As a special type of FTSM, transistor‐structured artificial synapse emulates important functions of a biological synapse to mimic brain‐inspired memory behaviors and nervous signal transmissions. This work reviews the recent development of the above mentioned FTSMs, with a focus on working mechanism and materials, and flexibility.
