A verify operation is performed on the one time programmable memory block to determine if it has been programmed. If any bits have been programmed, further programming or erasing is inhibited. In another embodiment, the memory block can be programmed and erased until a predetermined page or lock bit in the block is programmed. Once that page/bit is programmed, the one time programmable memory block is locked against further programming or erasing.
