Delayed XOR Rebuild With Priority In Multi-Protocol Products

A data storage device, comprising:

• a memory device;
• and
• a controller coupled to the memory device, wherein the controller is configured to:
• receive data to be programmed to the memory device using a first data storage device operating protocol;
• determine a protection requirement of the received data;
• program the received data to either a first block of the memory device or a second block of the memory device based on the determined protection requirement using the first data storage device operating protocol, wherein:
• the first block has a higher protection requirement than the second block;
• and
• the first block and the second block are associated with the first data storage device operating protocol;
• determine that the data storage device is operating using a second data storage device operating protocol, wherein the second data storage device operating protocol is different from the first data storage device operating protocol;
• generate parity data associated with the associated with the programmed received data while the data storage device is operating using the second data storage device operating protocol;
• and
• program the parity data and the received data to a third block, wherein the third block is associated with the second data storage device operating protocol.

A data storage device, comprising:

• memory means;
• and
• a controller coupled to the memory means, wherein the controller is configured to:
• detect that data stored in a first location of the memory means was programmed using a first data storage device operating protocol, wherein:
• the controller is operating under a second data storage device operating protocol during the detecting;
• and
• the data stored in the first location of the memory means comprises less parity data than a required minimum amount of parity data associated with the second data storage device operating protocol;
• generate parity data for the data stored in the first location of the memory means, wherein the generating occurs under the second data storage device operating protocol;
• program the generated parity data to a second location of the memory means;
• receive a read command for the data while the controller is operating under the second data storage device operating protocol;
• and
• read the generated parity data and the data from the memory means using the second data storage device operating protocol.
