Abstract
A controller for a one-time-programmable (OTP) memory is configured to, in response to a write request to program a single bit of an OTP value to the OTP memory, program a bit of the OTP value in the OTP memory, generate a set of PCBs corresponding to the OTP value, and program the PCBs into the OTP memory. Each PCB of the set of PCBs is generated as a logic function of a different subset of bits of the OTP value. The logic function only results in each PCB being programmed or remaining programmed in the OTP memory but not cleared. The OTP controller may be configured to, in response to the write request, program both the bit of the OTP value and a redundant bit, in which the set of PCBs includes a first PCB based on the bit and a second PCB based on the redundant bit.
