  • Patent number: 4858181
    Abstract: A semiconductor memory includes a memory cell (42) which utilizes a cross-coupled bipolar SCR latch. The latch includes two sense nodes (78) and (80). Sense node (78) has associated therewith an NPN transistor (82) and a PNP load transistor (84). Similarly, sense node (80) has associated therewith an NPN transistor (90) and a PNP load transistor (92) configured as an SCR. Each of these sense nodes is cross-coupled to the base of the NPN transistor connected to the opposite sense node. A forward biased PN junction is connected between an external Write circuit and the collector of each of the NPN transistors to provide an independent current path when changing from a low logic state to a high logic state. This decreases the recovery time when going from a saturated to a cut-off state for the NPN transistor.
