ABSTRACT:
High density static memory cells and arrays containing gated lateral bipolar transistors which can be latched in a bistable on state. Each transistor memory cell includes two gates which are pulse biased during the write operation to latch the cell. Also provided is a CMOS fabrication process to create the cells and arrays.
