Abstract

A SRAM storage cell has a NMOS transistor and a PMOS transistor connected with each other between a source of potential and ground. The sources, gates and gate back plates of the transistors are commonly connected and coupled to a storage node. The drain of the NMOS transistor is supplied with the potential, whereas the drain of the PMOS transistor is grounded. A pass NMOS transistor is connected between the storage node and bit and word lines. This storage cell configuration provides considerably reduced area compared to conventional static storage cells.
