A semiconductor device comprises a memory cell, a bit line, a sense amplifier operating between a first voltage and a second voltage higher than the first voltage, a transfer control circuit including a transfer transistor, and a write circuit writing data into the memory cell through the bit line based on the first voltage and a third voltage. The sense amplifier receives and amplifiers the signal voltage at a sense node when the transfer transistor controls the connection between the bit line and the sense node in response to a transfer control voltage. The third voltage is set to a voltage lower than the second voltage and higher than the transfer control voltage, and the sense node is set to a voltage higher than the transfer control voltage in an initial period of a read operation before the data of the memory cell is read out to the bit line. |
