Abstract
A memory cell includes two active load, pnp transistors, and two npn switching transistors. The collector and base regions of the switching transistors are cross coupled. Each of the load transistors have two collectors, with the base of each load transistor directly connected to only one of its two collectors. The additional collector prevents the switching transistors from heavily saturating and thus increases the speed of operation of the cell.
