Abstract:
A memory device includes a memory bank accessible via a plurality of memory addresses. The memory device further includes a fuse array including a plurality of fuse banks. A fuse bank of the plurality of fuse banks includes a fuse circuit, which includes a fuse latch having first input circuitry. The fuse latch is implemented to store a first bit of a first memory address received at the first input circuitry. The fuse circuit also includes a matching circuit coupled to the first input circuitry. The matching circuit is implemented to receive a first bit of a second memory address at the first input circuitry and to output, at output circuitry, a comparison result based at least in part on the first bit of the first memory address and the first bit of the second memory address.
