Abstract

A subsystem configured to write data to a static random access memory cell employs a single N-channel MOS device connected to ground in each leg of the bi-stable memory cell to overdrive the stored data. The subsystem implements the dual control required to effect matrix operation of the SRAM cell in the gate circuit of the single N-channel MOS device in the drive path. Specifically, the column select signal controls a semiconductor junction that interrupts the data connection to the gate. In this manner, the column select control is removed from the drive path, thus increasing drive strength. Further, a second semiconductor junction connects the gate of the single NMOS device in the drive path when the gate signal is interrupted.
