Temporary parity buffer allocation for zones in a parity group

A non-transitory computer-readable storage medium comprising instructions that, when executed by a processing device, cause the processing device to:

• allocate a temporary parity buffer to a parity group, wherein the temporary parity buffer is allocated for written and unwritten portions of memory in the parity group, and wherein the parity group comprises a plurality of zones and wherein each of the plurality of zones comprises a plurality of portions of memory;
• receive a write command, wherein the write command includes user data and is directed to a portion of memory included in a zone of the plurality of zones;
• receive parity group data from the temporary parity buffer for the parity group, wherein the parity group data includes parity data for zones of the plurality of zones;
• determine that a fullness of the zone satisfies a threshold fullness;
• in response to determining the fullness satisfies the threshold fullness, replace the zone in the parity group with a replacement zone by determining replacement parity group data using the parity group data and data written to the zone, wherein the replacement parity group data does not include parity data for the zone;
• and
• send the replacement parity group data to the temporary parity buffer.

A system comprising:

• a plurality of memory devices;
• and
• a processing device, operatively coupled with the plurality of memory devices, to:
• allocate a temporary parity buffer to a parity group, wherein the temporary parity buffer is allocated for written and unwritten portions of memory in the parity group, and wherein the parity group comprises a plurality of zones and wherein each of the plurality of zones comprises a plurality of portions of memory;
• receive a write command, wherein the write command includes user data and is directed to a portion of memory included in a zone of the plurality of zones;
• receive parity group data from the temporary parity buffer for the parity group, wherein the parity group data includes parity data for zones of the plurality of zones;
• determine that a fullness of the zone satisfies a threshold fullness;
• generate permanent parity group data for the plurality of zones including the zone in response to determining the fullness satisfies the threshold fullness;
• store the permanent parity group data in a non-volatile memory element;
• in response to generating the permanent parity group data, replace the zone in the parity group with a replacement zone by determining replacement parity group data using the parity group data and data written to the zone, wherein the replacement parity group data does not include parity data for the zone;
• and
• send the replacement parity group data to the temporary parity buffer.
