Abstract
A solid state drive controller includes a processor configured to couple to a plurality of non-volatile memory devices. The plurality of non-volatile memory devices are configured to store a plurality of system journals and a plurality of physical pages. The solid state drive controller also includes a volatile memory configured to store a logical-to-physical address translation map configured to enable the solid state drive controller to determine a physical location of at least one logical page. The processor is configured to maintain the plurality of system journals in the plurality of non-volatile memory devices, wherein each system journal defines physical-to-logical page correspondences for a predetermined range of the plurality of physical pages, and each system journal comprises an identification number that includes a portion of an address of a first physical page of the predetermined range of the plurality of physical pages.
