PROBLEM TO BE SOLVED: To provide a semiconductor memory device in which read is performed efficiently and high speed operation can be performed. SOLUTION: The semiconductor memory device has memory elements. word lines connected to the memory element, a pair of bit lines connected to the memory element and including selection side bit line connected to a selected bit line and non-selection side bit lines connected to memory elements being not selected, first and second sense amplifiers connected to the pair of bit lines, and a reset circuit in which the potential of the selection side bit line read by either of the first and the second sense amplifiers is made a reset potential of the next read cycle, the non-selection side bit line is made to coincide with the reset potential. thereby, the pair of bit lines is reset to the reset potential of the next read cycle.
