ABSTRACT:
A semiconductor memory device includes a power supply circuit which generates a write current, a write line to which a logic state is transferred, a first pass transistor connected between the power supply circuit and the write line, and a first register which connects to the write line, receives a logic state of the write line in an input state, stores the received logic state in a storage state, and controls an on/off state of the first pass transistor on the basis of the stored logic state.
