Abstract

A single-event upset tolerant sense latch circuit for sense amplifiers is disclosed. The single-event upset tolerant sense latch circuit includes a first set of isolation transistors, a second set of isolation transistors, a first set of dual-path inverters, a second set of dual-path inverters, and an isolation transistor. The first set of isolation transistors is coupled to a first bitline, and the second set of isolation transistors is coupled to a second bitline. The second bitline is complementary to the first bitline. The first set of dual-path inverters is coupled to the first set of isolation transistors, and the first set of dual-path inverters includes a first transistor connected to a second transistor in series along with a third transistor connected to a fourth transistor in series. The second set of dual-path inverters is coupled to the second set of isolation transistors, and the second set of dual-path inverters includes a fifth transistor connected to a sixth transistor in series along with a seventh transistor connected to an eighth transistor in series. The isolation transistor couples the first and second sets of dual-path inverters to ground.
