摘要:
A computing device includes a first set of non-volatile logic element arrays associated with a first function and a second set of non-volatile logic element arrays associated with a second function. The first and second sets of non-volatile logic element arrays are independently controllable. A first power domain supplies power to switched logic elements of the computing device, a second power domain supplies power to logic elements configured to control signals for storing data to or reading data from non-volatile logic element arrays, and a third power domain supplies power for the non-volatile logic element arrays. The different power domains are independently powered up or down based on a system state to reduce power lost to excess logic switching and the accompanying parasitic power consumption during the recovery of system state and to reduce power leakage to backup storage elements during regular operation of the computing device.
