Abstract
A semiconductor memory device that generates a data strobe reset signal for preventing ring-back of a data strobe signal, and an operation method thereof. The semiconductor memory device includes a pulse signal generating unit for generating first and second pulse signals by synchronizing a write instruction with first and second internal clock signals, a reset signal generating unit for generating a reset signal having an activation width setup in response to the first and second pulse signals, and a data strobe reset signal generating unit for generating a data strobe reset signal by shifting the second pulse signal as much as a predetermined burst length and limiting an activation period of the data strobe reset signal in response to the reset signal.
