ASYNCHRONOUS POWER LOSS HANDLING APPROACH FOR A MEMORY SUB-SYSTEM

Abstract:

The occurrence of an asynchronous power loss (APL) event is detected in a memory sub-system. In response, an APL handling operation is performed. The APL handing operation includes identifying a last written page at a first page location in a block of the memory device, wherein the last written page is associated with a memory cell of the memory device, copying data from the last written page and from a related page associated with the memory cell to a temporary storage area in the memory device, copying the data from the temporary storage area to a second page location in the block of the memory device, and providing a notification that the memory device has recovered from the APL event.
