SEMICONDUCTOR MEMORY DEVICE AND SEMICONDUCTOR MEMORY SYSTEM INCLUDING THE SAME |
摘要 |
A semiconductor memory device includes: an internal clock signal generation unit configured to generate an internal clock signal in response to an external clock signal; an internal data strobe signal generation unit configured to generate an internal data strobe signal in response to an external data strobe signal; a phase comparison unit configured to compare phases of the internal clock signal and the internal data strobe signal that are used in an enabled write path in response to an internal dummy write command with each other; and an output unit configured to output an output signal of the phase comparison unit. |
