Abstract

Host data is written to a set of pages of a page stripe of a storage area of a memory sub-system. A set of exclusive or (XOR) parity values corresponding to the host data written to a portion of the set of pages of the storage area is generated. An additional XOR parity value is generated by executing an XOR operation using the set of XOR parity values. Parity data including the set of XOR parity values and the additional XOR parity value is stored in a cache memory of the memory sub-system. The parity data is written to an available page stripe of the storage area.
