Abstract
A write amplifier power generating circuit includes a control unit for changing an output voltage. In a first write cycle in which a pair of bit lines are being amplified, a write operation is performed by an overdrive write method in which a high level from a write amplifier is set to a first voltage (for example, a power supply voltage). In a second write cycle after amplification in the pair of the bit lines has been completed, a write operation is performed by a write method in which the high level from the write amplifier is set to a second voltage (for example, an internal voltage).
