Abstract

Abstract PURPOSE:To cope easily with the support of a new memory element and the memory extension, by controlling an address to a memory array card having different type without changing the circuit of the control card. CONSTITUTION:The memory array card 2 is provided respectively with a capacity identification signal generating circuit 3, the circuit 3 generates a capacity identification signal 102 being an information signal relating to the number of memory elements and capacity mounted on the said card 2 and transmits the signal to an address control circuit 4 of the control card 1. The control circuit 4 converts an address signal from an external device based on the capacity identification signal 102 and produces the memory address matched to the card 2 in response to the type of the memory element and transmits it. For example, the memory array card 2 having different type as TYPE 1, 2, 3 are controlled with the same control card 1.
