Abstract
A write voltage generation circuit includes: a power supply terminal that receives an external power supply voltage; a boosting circuit that boosts the external power supply voltage to generate a boosted voltage; and a selector that selects either one of the external power supply voltage and the boosted voltage, and outputs the selected voltage as the write voltage. The selector selects the external power supply voltage as the write voltage in a first part of a write period for writing data to a memory cell, and selects the boosted voltage as the write voltage in a latter part of the write period.
