Abstract: A data storage device and method for operating a non-volatile memory including device based space allocation and host-based mapping table searching. In response to a write command from a host that indicates a write logical address in metadata in the write command, a controller at the device end determines a write physical address and allocates the non-volatile memory to provide a space to store write data at the write physical address. The controller transmits the write physical address to the host so the host can establish a mapping table on the host.

The metadata programmed at the device end is read back with the read data for read data verification at the host end.
