Abstract
Techniques to recover data from an indirected non-volatile memory system after unexpected power failure, as, e.g., NAND memory in electronic devices are disclosed.
Claims14
A method to recover the state of data stored in NAND memory after power failure in an electronic device, comprising:
- detecting, during power failure recovery, a page state associated with a NAND page;
- and
- determining whether to include the NAND page in an L2P rebuild operation based at least in part on the page state associated with the NAND page.
A system to recover the state of data stored in NAND memory after power failure in an electronic device, comprising:
- logic to detect, during power failure recovery, a page state associated with a NAND page;
- and
- logic to determine whether to include the NAND page in an L2P rebuild operation based at least in part on the page state associated with the page.
