DEFERRED ECC (ERROR CHECKING AND CORRECTION) MEMORY INITIALIZATION BY MEMORY SCRUB HARDWARE

Initialization of a memory can have different phases, first initializing a portion of memory for BIOS (basic input/output system) and initializing other portions of memory while the BIOS is operating. The initialization of the memory can be performed by the error scrub engine. In a first mode of operation, the scrub engine can initialize memory locations, then transition to performing scrub operations.
