Non-volatile array wakeup and backup sequencing control
Individual first ones of a plurality of non-volatile logic element arrays are designated to restore first in response to entering a wakeup or restoration mode. These non-volatile logic element arrays include instructions for an order in which other non-volatile logic element arrays are to be restored next. So configured, the processing device can be set to have one or more NVL arrays restored first, which arrays are pre-configured to guide further wakeup of the device through directed restoration from particular NVL arrays. Certain NVL arrays can be skipped if the functions stored therein are not needed, and the order of restoration of others can be tailored to a particular wakeup time and power concern through restoration in parallel, serial, or combinations thereof.
