| Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a memory system, capable of shortening the processing time in rearrangement of data (cached data) written in a memory regardless of addresses in the order of addresses. SOLUTION: The memory system comprises a nonvolatile semiconductor memory including first and second original blocks OBM1 and OBM2 consisting of n-pieces of writing unit areas and first and second sub-blocks SB1 and SB2 consisting of a plurality of writing unit areas. A controller writes data with first to p-th (p is a natural number satisfying p |
