Abstract:
This invention discloses a static random access memory (SRAM) cell which comprises a pair of cross-coupled inverters having a first storage node, a first NMOS transistor having a source and a drain connected between the first storage node and a bit-line, a second NMOS transistor having a source and a drain connected between a gate of the first NMOS transistor and a word-line, the second NMOS transistor having a gate connected to a first column select line, and a third NMOS transistor having a source and a drain connected between a ground (VSS) and the gate of the first NMOS transistor, and a gate connected to a second column select line, the second column select line being complementary to the first column select line.
