ABSTRACT:
Disclosed herein is a semiconductor memory device for reducing a current consumption used for operating a write command or a read command. The semiconductor memory device includes a global data latch unit for latching a global data loaded on a global data line in response to a first write enable signal to thereby generate a global latch data; a local data write driving unit for receiving the global latch data to output a local data to a local data line in response to a second write enable signal; and a write driver control unit for generating the first write enable signal and the second write enable signal to inactivate the first write enable signal when a write operation is not performed.
