Reduced parity data management

Abstract:

A method includes receiving, by a memory sub-system, host data to be written to a plurality of blocks of a memory device associated with a memory sub-system, where each of the plurality of blocks are coupled to one of a plurality of word lines of the memory device. The method can further include generating parity data for each word line of the block; dividing the parity data into one of either a first word line parity set or a second word line parity set; generating a reduced parity data set with exclusive or parity values for the first word line parity set and for the second word line parity set; and writing the reduced parity data set in the memory sub-system.
