摘要：
A nonvolatile memory device includes a plurality of memory controllers. Each of the memory controllers has an aggregation processing part and an aggregation synchronization part. Based on a signal from the aggregation synchronization part, the aggregation processing part aggregates valid data of a temporary physical block into another physical block. When one of the memory controllers requires an aggregation process, the aggregation synchronization part sends a synchronization signal to the other memory controller, so that the aggregation process is simultaneously carried out by the other memory controller. Thus, in the nonvolatile memory device having a plurality of memory controllers, it is possible to reduce the time required for the aggregation process and carry out a high-speed writing process.
