PROBLEM TO BE SOLVED: To prevent consumption of a needless current by eliminating needless precharege operation at write operation of a semiconductor memory apparatus. SOLUTION: This local input/output line precharge circuit of the semiconductor memory device comprises a precharge control unit which responds to a continuous write signal activated when write operation continues and outputs a precharge control signal to precharge a pair of local input/output lines, an equalization unit precharging and equalizing the pair of local input/output lines in response to the precharge control signal, and a data output unit outputting data signals of a global input/output lines to the pair of local input/output lines in response to output signal of the equalization unit.
