Abstract:
A differential latch-based one time programmable memory cell is provided. The differential latch-based one time programmable memory cell includes a differential latching amplifier having a first set of fuse devices coupled to the first input and a second set of fuse devices coupled to the second input. Only one set of fuse devices can be programmed in a memory cell. If one or more fuse devices in a set of fuse devices are programmed, the side having the programmed fuse will present a lower voltage at its input to the differential latching amplifier. Differential latching amplifier outputs a “0” or a “1” depending on the side having the programmed fuse.
