Abstract
A semiconductor memory device performs a reset operation at a wafer state by using a signal input through an address pin in a test mode. The semiconductor memory device includes a buffer for transferring a reset command in response to a reset-active signal and a test reset signal, a test-reset entry signal generation unit for generating an internal test-reset entry signal in response to the test reset signal, and a rest signal driving unit for driving an active signal of an output signal of the buffer and the internal test-reset entry signal as an internal reset signal for a reset mode entry.
