Abstract

A memory apparatus including a back board having a lower address side and an upper address side, and a plurality of memory cards installed on the back board. Each memory card comprises a lower address side detecting signal pin for determining whether that memory card is installed on the lower address side of the back board, capacity detecting signal pins for notifying other memory cards of the capacity of that memory card, address signal pins, connected to an address signal line, and an address assigning circuit. When a memory card is installed on the lower address side of the back board, the capacity detecting signal pins and address signal pins assign an address to that memory card starting from a minimum address on the lower address side, and assign and address to another memory card which is installed on the upper address side starting with an address following the maximum address of the memory card installed on the lower address side.
