Claim 15:
16. An apparatus comprising:
a row decoder including:
a common power supply circuit configured to provide a common power supply voltage to a common power supply node responsive to a plurality of control signals; and

a bank including:
a first plurality of memory cells;
a second plurality of memory cells;
first sense amplifiers coupled to the first plurality of memory cells and further coupled to the common power supply node;
second sense amplifiers coupled to the second plurality of memory cells and further coupled to the common power supply node;
a first power control circuit coupled to the first sense amplifiers at the common power supply node ; the first power control circuit configured to receive the plurality of control signals and further configured to provide the common power supply voltage with a first drive strength to the common power supply node responsive to the plurality of control signals; and
a second power control circuit coupled to the second sense amplifiers at the common power supply node, the second power control circuit configured to receive the plurality of control signals and further configured to provide the common power supply voltage with a second drive strength to the common power supply node responsive to the plurality of control signals,

wherein the first and second drive strengths are different responsive to activation of a first control signal of the plurality of control signals, and
wherein the common power supply circuit is configured to have a third drive strength and a fourth drive strength different from each other responsive to an activation of the first control signal and an activation of a second control signal after the activation of the first control signal respectively.
