Abstract
There are provided power supply drivers to respective sense amplifier bands, and each the power source drivers is activated when sense amplifier circuits of a corresponding sense amplifier band operate. A power supply driver supplies a current to a corresponding sense power supply line when activated according to a control voltage from an active sense amplifier power supply/control circuit. Sense amplifier power supply lines and an array power line are laid over on a memory mat in a meshed shape arrangement and subject to current supply when the active sense amplifier power supply/control circuit operates. Reduction in level of a sense amplifier power supply voltage on a sense amplifier power supply line is exactly suppressed independently of a distance from an array power supply voltage generation circuit included in the active sense amplifier power source control circuit.
