METHOD AND APPARATUS FOR SEVERE MEMBRANE EARLY TREATMENT

摘要

A device is described that includes a memory controller for coupling to a multilevel memory characterized by a faster higher level and a slower, lower level. The memory controller has early downgrade logic circuits for downgrading a page from the higher level to the lower level, without system software having to instruct the memory controller to downgrade the page and before the system software upgrades another page from the lower level to the higher level.
