Abstract:
Systems and methods are disclosed, including, in a storage system comprising control circuitry and a memory array having multiple groups of memory cells, storing a first physical-to-logical (P2L) data structure for a first physical area of a first group of memory cells in a second physical area of the first group of memory cells, such as when resuming operation from a low-power state, including an asynchronous power loss (APL). The first group of memory cells can include a super block of memory cells. A second P2L data structure for the second physical area of the first group of memory cells can be stored, such as in a metadata area of the second physical area and an address of the first P2L data structure can be stored in the second P2L data structure.
