Abstract
A one-time programmable (OTP) latch circuit can include a single OTP device capable of storing a logic value in a nonvolatile fashion, or only two OTP devices in the event redundancy is desired. A latch section can latch a data value based on a comparison between a current drawn according to the one OTP device, and a reference current generated without and OTP device. An OTP device can include a gate oxide antifuse (GOAF) device.
