Abstract
A semiconductor memory device (M) includes a memory array (MA) having a plurality of memory cells, a redundancy array (RA) having a plurality of memory cells, a non-volatile redundancy information memory (NVR) having a plurality of memory cells for storing redundancy information, and a redundancy control unit (RU) for selecting either memory cells in the memory array (MA) or memory cells in the redundancy array (RA). In one example, the non-volatile redundancy information memory (NVR) is connected directly to the redundancy control unit (RU) by means of at least one sense amplifier (SA).
