Block status parity data in memory

An apparatus, comprising:

• a non-volatile memory comprising a plurality of blocks of memory;
• and
• a controller coupled to the non-volatile memory and configured to:
• store block status data associated with at least one block of the plurality of blocks of the non-volatile memory that indicates a status of the at least one block of memory within a register in the controller;
• store parity data that corresponds to the block status data within the controller;
• prior to writing the block status data to the non-volatile memory, compare the stored block status data associated with at least one block of the non-volatile memory to the parity data;
• and
• determine the at least one block of the non-volatile memory is valid or to reload the stored block status data responsive to the comparison of the stored block status data to the parity data.

An apparatus, comprising:

• non-volatile memory;
• and
• controller coupled with the memory and configured to cause the apparatus to:
• store block status data associated with the at least one block of the non-volatile memory that indicates a status of the at least one block of memory within a register in the controller;
• store parity data that corresponds to the block status data within the controller;
• compare the stored block status data within the register to the parity data;
• receive and store block status data associated with another block of memory of the non-volatile memory;
• responsive to receiving the update, compare the stored block status data within the register to the parity data within the controller;
• and
• write the stored block status data to the non-volatile memory responsive to the block status data matching the parity data.
