Abstract
A multi-power-domain emulated persistent memory resource system includes a memory interface/data mover subsystem coupled to a second memory subsystem in a second power domain, and a microvisor subsystem coupled to the memory interface/data mover subsystem and a first memory subsystem in a first power domain that is different than the second power domain. The microvisor subsystem presents an emulated persistent memory resource to a client device using the first memory subsystem, and monitors metadata for the first memory subsystem to identify modification(s) of data in the first memory subsystem. In response, the microvisor subsystem uses the memory interface/data mover subsystem to copy the data from the first memory subsystem to the second memory subsystem. Following unavailability of the first power domain and corresponding loss of the data on the first memory subsystem, the memory interface/data mover subsystem copies the data from the second memory subsystem to the first memory subsystem.
