ABSTRACT:
An address value is set in an address counter by a command supplied from an external circuit via data input/output pins. For this reason, no special-purpose address input pins need be arranged, and the number of pins need not be increased even when the capacity of a semiconductor memory chip is increased. Since the address value is automatically incremented by the address counter, when continuous addresses are to be accessed, the addresses need not be re-set, and a serial access can be efficiently realized. Since a chip address is assigned to each semiconductor memory chip according to a potential setting state of a chip select signal, no external control circuit for selecting a semiconductor memory chip is required, and a control operation can be simplified.
