Managing storage of multiple plane parity data in a memory sub-system
Abstract:
Host data to be written to a storage area including a set of multiple planes of a memory device is received. A first parity generation operation based on a portion of the set of multiple planes of the host data to generate a set of multi-plane parity data is executed. The set of multi-plane parity data is stored in in a cache memory of a controller of a memory sub-system. A second parity generation operation based on the set of the multiple planes of the host data to generate a set of multi-page parity data is executed. The set of multi-page parity data in the cache memory of the controller of the memory sub-system is stored. A data recovery operation is performed based on the set of multi-plane parity data and the set of multi-page parity data.
