Memory cell circuit with single bit line latch

Abstract

A memory cell circuit for a CMOS static RAM is provided, which includes a latch portion for holding logic high or logic low data depending on the potential of a single bit line, and a transfer gate having a first terminal connected to the latch portion and a second terminal connected to the single bit line, the transfer gate electrically connecting or disconnecting the first and second terminals in response to a selection signal, wherein the transfer gate includes a first transistor and a second transistor connected in parallel between the first and second terminals, both of the first and second transistors being activated at a data write operation, while one of the first and second transistors being activated at a data read operation.

Dependencies are inferred from the claim text.
