Abstract
A method and apparatus for programming a one-time programmable (OTP) memory device is disclosed that allows for resuming and recovering from an interrupted programming cycle (e.g. due to loss of power or user interaction). Upon re-initiation of a programming cycle with the same memory range, a programming controller may detect the memory address where interruption occurred, and resume programming from that address. If the programming interruption resulted in an incorrectly programmed word at the interrupted address, a word repair register may be mapped to the corrupted address to enable correction of that word. The remainder of the memory range may then be programmed normally.
