Abstract

PURPOSE:To confirm the packing state of a memory in terms of a software, by providing a memory-based storage part. CONSTITUTION:Various types of memories are divided into memory modules, and a memory-based storage part 16 is provided to each module to store the type of the memory. At the same time, a gate 17 for part 16 plus a control circuit 18 that opens/closes the gate 17 are added to read the contents of the part 16. When a memory is packed, switch groups SW1 and SW2 of the part 16 are set by the type of the memory. Then an optional address is allotted to the part of an address buffer 12 by switching a switch, etc. After packing a memory in such way, the memory is connected to a processor to inspect both the address plus the type and packing state of the memory in terms of a software.
