摘要： Described herein are apparatus, system, and method for providing memory access control to protect software (e.g., firmware backup) and other data. The method comprises providing, by a processor, a protected storage area in a memory for storing backup image of software; detecting corruption in the software; accessing the backup image of the software from the protected storage area; and updating the corrupted software using the backup image, wherein the protected storage area is a reserved storage area of the memory.

摘要： A mass storage system employs a paging table for memory page redirection and maintains the paging table for power loss recovery (PLR) using a FIFO queue of paging table (L2P) segments to be written to non-volatile memory. The FIFO queue identifies a sequence of the L2P segments in conjunction with sequence number and marking data of the affected segments for recreating the paging table. Upon power failure, a power loss recovery (PLR) mechanism scans for the last segment written based on the FIFO queue. The PLR process recovers unwritten paging table entries by replaying the corresponding changes in the order defined by the sequence numbers. The recovery process continues for each sequence number in the current context, until the L2P information in the paging table is recreated to the point just prior to power loss.

摘要： Various embodiments are directed to apparatuses and methods for faster solid state drive (SSD) boot-up. On boot-up, SSD control algorithms may load non-logical to physical (L2P) parts of a context and signal the system that the SSD is ready. The context may comprise various state data pertaining to the SSD. After signaling that the SSD may be ready to receive access requests, the SSD control algorithms may begin loading segments of the L2P table sequentially. Access to the L2P table may be blocked, however, when a requested segment has not yet been loaded. In such cases, the SSD control algorithms may then load the requested segment out of turn and then service the access request.
