Abstract
A memory circuit includes a memory array comprising first memory cells and second memory cells, each of the first memory cells configured to store a data bit, and each subset of the second memory cells configured to store repair bits, the repair bits indicating a location of a corresponding first memory cell and a random bit; register circuits, the register circuits configured to transfer or latch the plurality of repair bits; a compare circuit coupled to the register circuits, the compare circuit configured to provide a match signal, in response to determining that an address signal matches the location of the corresponding first memory cell indicated by the repair bits; and a multiplexer coupled to the compare circuit, the multiplexer configured to output the random bit instead of the data bit stored by the corresponding first memory cell, based on the match signal.
