SEMICONDUCTOR MEMORY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a semiconductor memory device having low current consumption.SOLUTION: A semiconductor memory device according to an embodiment includes: a first current control transistor whose one terminal is connected to a first power supply potential; a bit line that is connected to the other terminal of the first current control transistor; a source line that is connected to a second power supply potential; and a plurality of word lines. When data is read from a memory cell transistor that is connected between the bit line and source line and that uses the word lines as a control gate electrode, a potential to be applied to a control electrode of the first current control transistor increases with time.
