Abstract: A one-time programmable (OTP) circuit. The OTP circuit includes a non-volatile OTP memory disposed on a first circuit die. The OTP memory includes a floating gate terminal. The OTP circuit also includes a cross-coupled latch disposed on the first circuit die and coupled to the OTP memory and volatile memory input circuitry disposed on the first circuit die and coupled to the cross-coupled latch. The volatile memory input circuitry is configured to receive a test value and write the test value into the cross-coupled latch. The OTP circuit is configured to receive a programming command and store the test value in the OTP memory in response to receipt of the programming command.
