Apparatus, computer program product, system, and method for managing multiple regions of a memory device

A system, comprising:

• a host system;
• and
• a non-volatile memory device in communication with the host system, comprising:
• a plurality of storage dies;
• a controller to:
• assign a first group of logical bands to a first memory region in which metadata is to be stored;
• assign a second group of logical bands to a second memory region to which host data is written, wherein the second group of logical bands is larger than the first group of logical bands;
• indicate a mapping of physical bands in the storage dies to the first group of logical bands and the second group of logical bands;
• and
• return, to the host system, indication of the first group of logical bands for the first memory region and the second group of logical bands for the second memory region, wherein the host system directs requests for metadata to logical addresses in the first group of logical bands and directs request for file data to logical addresses in the second group of logical bands.

A method for assigning addresses in a non-volatile memory device comprised of a plurality of storage dies, comprising:

• assigning a first group of logical bands to a first memory region in which metadata is to be stored;
• assigning a second group of logical bands to a second memory region to which host data is written, wherein the second group of logical bands is larger than the first group of logical bands;
• indicating a mapping of physical bands in the storage dies to the first group of logical bands and the second group of logical bands;
• and
• returning, to a host system, indication of the first group of logical bands for the first memory region and the second group of logical bands for the second memory region, wherein the host system directs requests for metadata to logical addresses in the first group of logical bands and directs request for file data to logical addresses in the second group of logical bands.
