Abstract
A BICMOS latch driver L/D is used to implement a BICMOS gate array memory cell (FIG. 2b). The memory cell includes a latch formed by cross-coupled invertors (INV1 and INV2). The driver stage is formed by an NPN transistor Q0 and an n-channel transistor MN3. The relatively stronger bipolar transistor is used to pull the output of the BICMOS latch/driver HI, while, for most applications, the relatively weaker n-channel device has sufficient strength to pull the output low. A WRITE port (WP) that interfaces to the WRITE bitline, and a READ port (RP) that interfaces to the READ bitline.
