PURPOSE:To shorten a memory starting time by directly accessing a backup memory to start a memory in a storage part. CONSTITUTION:Bus switching parts 201 to 20n in a common backup memory part 2 connect backup memories 211 to 21n from a common bus 4 to local buses 51 to 5n based upon switching signals 5l1 to 5ln outputted from a reference processing part 1. Memory writing parts 301 to 30n in storage parts 31 to 3n store data read out from the backup memories 211 to 21n in memories 311 to 31n through the local buses 51 to 5n. Since the data in the backup memories 211 to 21n are directly written in the memories 311 to 31n, the memory starting time can be shortened. |
