Abstract: The present disclosure relates to integrated circuits, and more particularly, to a method for identifying unprogrammed bits for one-time-programmable memory (OTPM) and a corresponding structure. In particular, the present disclosure relates to a structure including: a read circuit configured to perform at least one read operation at an address for a twin-cell one-time-programmable-memory (OTPM); and a comparison circuit configured to identify whether at least one bit of the address for the twin-cell OTPM has been programmed based on the at least one read operation.
