FINFET MEMORY DEVICE WITH DUAL SEPARATE GATES AND METHOD OF OPERATION

摘要

A FinFET device comprises a front gate (FG) and a separate back gate (BG) disposed on opposite sides of the fine. The fin structure may act as a floating body of a volatile memory cell. The front and back gates may be doped with the same or opposite polarity, and may be biased oppositely. A plurality of FinFETs may be connected in a memory array with single column erase, or double column erase capability.
