ABSTRACT:
A semiconductor memory unit employed in a microcomputer system includes an address counter for fetching address information from a microcomputer in response to an address latch signal from the microcomputer. The address counter further receives an updating control signal from the microcomputer and updates the fetched address information by one in response to each updating control signal. The memory device further includes a program memory for storing a string of instructions and an address decoder circuit for accessing the program memory in response to the address information from the address counter. Since the address information is updated by the updating control signal, the microcomputer fetches and executes the successive instructions without supplying the respective address information to the memory device.
