Abstract

PURPOSE:To improve the efficiency of the storage capacity of a virtual memory system, by using an address table (TLB) storage part as a logging information storage part when the system is down. CONSTITUTION:If a TLB storage part 3 is accessed by a prescribed bit of a logical address and the bit 0 of an entry shows insignificance, or if the 1st-4th bits become dissident with bits 0-3 of the logical address, a system is judged to be shut down. Then, the storage part 3 is placed in a logging information storage state which shows a system stop state, and a physical address is generated with CS control information in a main storage device MM. Therefore, a specific memory for logging information storage is unnecessary and the efficiency of memory capacity is improved.
