ABSTRACT:
The multi-port memory device includes a mode input/output controller for receiving a flag signal and generating a self-refresh entry signal and a self-refresh escape signal, a refresh interval signal generator for providing a self-refresh interval signal notifying a self-refresh interval in response to the self-refresh entry signal and the self-refresh escape signal, a refresh cycle signal generator for periodically generating a cycle-pulse signal during an activation of the self-refresh interval signal, an internal refresh signal generator for producing an internal refresh signal in response to the self-refresh entry signal and the cycle-pulse signal, and an internal address counter for generating an internal address in response to the internal refresh signal.
