MEMORY DEVICE AND INTEGERATED CIRCUIT

摘要

The memory device includes: a nonvolatile memory which is operated using a plurality of power sources and outputs stored repair information in response to a boot-up signal; a plurality of registers which store the repair information outputted from the nonvolatile memory; a plurality of memory banks which replace a normal cell with a redundancy cell using the repair information stored in the registers corresponding to the memory banks among the registers; and a boot-up control circuit which activates the boot-up signal when the levels of the power sources are stabilized.
