Abstract
Data stored in a volatile memory subsystem is backed up redundantly into first and second channels of a non-volatile memory subsystem. The data is retrieved from the volatile memory subsystem upon detection of a trigger condition indicative of real or imminent power loss or reduction and multiple copies are stored in dedicated non-volatile memory channels. The stored copies may be error checked and corrected, and re-written if necessary. The redundantly backed up data can be subsequently retrieved from the non-volatile memory subsystem, error-corrected, and an error-free copy communicated to the volatile memory subsystem.
