METHOD FOR GENERATING RESET SIGNAL IN SEMICONDUCTOR MEMORY DEVICE

摘要

PURPOSE: A method for generating reset signal in semiconductor memory device is provided, which is capable of reducing a layout area occupied by a stabilization circuit and power consumption. CONSTITUTION: A precharge command is received to precharge all banks of a semiconductor memory device(310). A reset signal is activated with the first level based on the received precharge command(320). After receiving the precharge command, a refresh command is received to refresh the semiconductor memory device(330). After receiving the refresh command, a mode setting command is received to reset the semiconductor memory device(340). The reset signal is inactivated with the second level base on the received mode setting command(350).
