Abstract
A media management operation is executed to write data from a source block of a cache memory to a set of pages of a destination block of a storage area of a memory sub-system. An entry of a data structure identifying a page count corresponding to the source block of the cache memory is generated. A power loss event associated with the destination block of the storage area is identified. A data recovery operation is executed using the data stored in the source block to complete the write to the destination block. The data is erased from the source block in response to the page count satisfying a condition.
