Abstract
A memory to which a bit line potential step-down technique is applied is provided. The memory includes an IO block including first transistors which control potentials of first bit lines provided with respect to columns of memory cells, and first logic gates which control the first transistors. The drain or source of each first transistor is connected to an input of the corresponding first logic gate, and the gate of each first transistor is connected to an output of the corresponding first logic gate. The first transistors are driven by pulses.
