Classification: CPC G | IPC G

Claim 10:
11. A data storage device, comprising:
a volatile memory;
a plurality of non-volatile memory devices;
a processor configured to execute instructions to:
set, responsive to determining to decompose and recompose the data storage device, a flag indicating that flushing a virtual-to-physical (V2P) mapping table of a data storage device is unnecessary for a next reset command;
download a firmware update to the data storage device;
activate the firmware update in the data storage device;
receive the next reset command, wherein reset commands normally include a step to flush the V2P mapping table from the volatile memory to at least one non-volatile memory device of the plurality of non-volatile memory devices;
determine, prior to executing flushing of the V2P mapping table for the next reset command, whether the flag is set;
forgo, responsive to determining that the flag is set and executing the next reset command, the step to flush the V2P mapping table to the at least one non-volatile memory device; and
complete the reset command without flushing the V2P mapping table, wherein:
the V2P mapping table is cleared from the volatile memory by a power cycle of the reset command; and
a provisioning time of decomposing and recomposing the data storage device is reduced.
