INTEGRATED CIRCUIT AND MEMORY DEVICE

摘要

A memory device comprises a boot-up control unit for controlling a boot-up operation when an initialization signal is activated and ignoring the initialization signal after activating a completion signal; a nonvolatile memory unit for storing repair data and for outputting the repair data which is stored during a boot-up operation section controlled by the boot-up control unit; multiple registers for storing the repair data outputted from the nonvolatile memory unit; multiple memory banks for replacing normal cells into redundancy cells using the repair data stored in the corresponding registers; and a verification unit for generating the completion signal which informs the completion of the boot-up operation.
