Fig. 1: Difference between flash memory and PSD-based optoelectronic memory in terms of the device structure and write and erase processes.
From: Non-volatile optoelectronic memory based on a photosensitive dielectric
a Flash memory structure. b Write and erase processes in the flash memory. c Structure of the PSD-based optoelectronic memory. d Write and erase processes in the PSD-based optoelectronic memory. The solid balls represent the electrons, and the hollow balls represent the holes. The arrows represent flow directions of electrons or holes.
