Zusammenfassung:An integrated circuit comprises a power supply input pin receiving an off-chip supply voltage having a variable current, an on-chip power source powered by the off-chip supply voltage and providing a regulated current, a memory array, and a set of one or more circuits coupled to the memory array and powered by the regulated current from the on-chip power source. The IC can include control circuitry performing memory operations on the memory array, said control circuitry powered by at least the off-chip supply voltage from the power supply pin.
