Abstract
A self refresh operation control device, for use in a semiconductor memory device, includes a self refresh pulse signal generation block for generating a self refresh pulse signal, a self refresh entry signal and a self refresh mode clock enable signal in response to a clock enable signal, a self refresh signal, a self refresh end signal and a test mode signal, wherein the self refresh pulse signal is generated during the inactivated period of the clock enable signal by using the test mode signal; a normal mode clock signal generation block for generating a normal mode clock signal and a counter reset signal in response to the clock enable signal, the self refresh mode clock enable signal, a test mode signal and the self refresh signal; and an internal row address counter in response to the self refresh pulse signal and the counter reset signal for generating internal addresses for use in the self refresh operation.
