Abstract:
1. A method for controlling power consumption, comprising: a logic block; a power source; a phase change switch adapted to couple the power source to the logic block in accordance with the phase change switch being configured in a low impedance state and adapted to decouple the power source from the logic block in accordance with the phase change switch being configured in a high impedance state, said phase change consisting of a crystalline to amorphous phase change; a programming circuit coupled to the phase change switch and adapted to provide a programming voltage to the phase change switch, wherein the phase change switch is configured in accordance with the programming voltage; and a voltage generation circuit adapted to supply a first boosted voltage and a second boosted voltage to the programming circuit, wherein the second boosted voltage is greater than the first boosted voltage and the programming voltage corresponds to one of the first boosted voltage, the second boosted voltage, and ground.
