Abstract

A memory device includes a memory, an address latch, a built-in incrementer, and an address decoder. The address decoder has a mapping register which assigns the memory to a predetermined address. The address decoder further includes a standby signal producer which detects whether or not the address latch addresses an address specified by the mapping register and which sets the memory device to a standby state of a low power consumption when such is not detected. The memory device can be set to a standby state even when the memory device is connected to a microcomputer with a protocol by which an address of the memory is not outputted each time. This arrangement enables to save power consumption of the computer, to decrease the load of a power supply circuit in a microcomputer applied apparatus and to make the apparatus compact.
