US Patent 11994984 Namespace mapping optimization in non-volatile memory devices

A computer storage device having a host interface, a controller, non-volatile storage media, and firmware. The firmware instructs the controller to: store a namespace map to map blocks of logical addresses defined in a namespace to first blocks of logical addresses defined in a capacity of the non-volatile storage media; without changing a size of the namespace, adjust the namespace map to map the blocks of the logical addresses defined in the namespace to second blocks of the logical addresses defined in the capacity of the non-volatile storage media (e.g., to consolidate blocks for performance improvement); and translate the logical addresses in the namespace to physical addresses for the non-volatile storage media using the namespace map.
