Abstract

See full text

At least one method, apparatus and system disclosed involves a memory device having a memory cell comprising NMOS only transistors. An SRAM bit cell comprises a first pass gate (PG) NMOS transistor coupled to a first bit line signal and a word line signal; a second PG NMOS transistor coupled to a second bit line signal and the word line signal; a first pull down (PD) NMOS transistor operatively coupled to the first PG NMOS transistor; a second PD NMOS transistor operatively coupled to the second PG NMOS transistor; a first pull up (PU) NMOS transistor operatively coupled to the first PD NMOS transistor; and a second PU NMOS transistor operatively coupled to the second PD NMOS transistor. Each of the back gates of the first and second PU NMOS transistors are coupled to a predetermined voltage signal for biasing the first and second PU NMOS transistors.
