Abstract
Power control circuitry for a data processor supplies a memory array with a supply voltage corresponding to a memory performance level. The performance levels include a full performance level and a power-saving performance level. Voltage sensing circuitry senses a voltage level of the memory array and outputs a power status signal. The power status signal is used to determine when the memory array is awake and can be accessed.
