Claim 17:
18. The apparatus of claim 16, wherein the common power supply circuit is a first common power supply circuit configured to provide the common power supply voltage that is a first common power supply voltage to the common power supply node that is a first common power supply node responsive to the plurality of control signals that is a first plurality of control signals,
the apparatus further comprises:
a second common power supply circuit configured to provide a second common power supply voltage to a second common power supply node coupled to the first sense amplifiers and the second sense amplifiers responsive to a second plurality of control signals,
a third power control circuit in the bank coupled to the first sense amplifiers at the second common power supply node, the third power control circuit configured to receive the second plurality of control signals and further configured to provide the second common power supply voltage to the second common power supply node responsive to the second plurality of control signals; and
a fourth power control circuit in the bank coupled to the second sense amplifiers at the second common power supply node, the fourth power control circuit configured to receive the second plurality of control signals and further configured to provide the second common power supply voltage to the second common power supply node responsive to the second plurality of control signals,

wherein the third and fourth power control circuits are configured to provide the second common power supply voltages with fifth and sixth drive strengths respectively responsive to activation of a third control signal of the second plurality of control signals, and
wherein the second common power supply circuit is configured to provide the second common power supply voltage with a seventh drive strength and an eighth drive strength different from each other responsive to an activation of the third control signal and an activation of a fourth control signal after the activation of the third control signal respectively.
