GAT block allocation

A method comprising:

• allocating, with an electronic controller, a first region of a memory for storing data received from an external electronic device, the first region including a first memory die of a plurality of memory dies;
• allocating, with the electronic controller, a second region of the memory for storing metadata associated with the data received from the external electronic device, the second region including a second memory die of the plurality of memory dies that is different from the first memory die;
• receiving, with the electronic controller, a write command from the external electronic device, the write command including first data to be written to the memory;
• controlling, with the electronic controller, the memory to write the first data to the first region;
• generating, with the electronic controller, first metadata associated with the first data;
• and
• controlling, with the electronic controller, the memory to write the first metadata associated with the first data to the second region,
• wherein the metadata associated with the data received from the external electronic device includes logical-to-physical (L2P) mapping information that maps to storage locations of the data received from the external electronic device.

A data storage device comprising:

• a memory having a plurality of memory dies, wherein each memory die of the plurality of memory dies includes a plurality of memory planes, and
• the memory is configured to perform asynchronous independent plane reads (AIPR) on the plurality of memory dies;
• and
• an electronic controller configured to:
• receive a write command from an external electronic device, the write command including first data to be written to the memory,
• control the memory to write the first data to a first region of the memory,
• generate first metadata associated with the first data, the first metadata including primary metadata and secondary metadata, and
• control the memory to write the first metadata associated with the first data to a second region of the memory by
• controlling the memory to store the primary metadata to a first memory plane in the second region, and
• controlling the memory to store the secondary metadata to a second memory plane in the second region that is different from the first memory plane, the first memory plane and the second memory plane being located in a same memory die,
• wherein the first metadata includes logical-to-physical (L2P) mapping information that maps to a storage location of the first data received from the external electronic device.
