Abstract: A semiconductor memory device is kept in a busy state by controlling a ready/busy pad when a detection signal is output since an external voltage is less than a reference voltage, prevents generation of an operating voltage by a pump circuit by preventing generation of a pump clock, and resets a microcontroller by preventing generation of micro clock. Accordingly, the semiconductor memory device may be prevented from malfunctioning through a series of operations when the external voltage is less than the reference voltage.
