Abstract
Transfer transistors are connected midway on respective bit lines of a bit line pair. Memory cells are provided for a first bit line pair and a second bit line pair partitioned by the transfer transistor, and a sense amplifier is connected to the first bit line pair. When a memory cell connected to the first bit line pair is selected, the transfer transistor turns off. Therefore, the potential difference appears only on the first bit line pair, with the potentials amplified by the sense amplifier. In this state, the potential of the second bit line pair is not changed and not amplified.
