Abstract:
A storage system includes a host device and a storage device. The host device generates a write command, a logical address of write data corresponding to the write command, and a selective purge tag indicating that the write data are targeted for selective purge. The storage device receives the write command, the logical address, and the selective purge tag, stores write data, and logically erases the stored write data upon receiving an erase command from the host device. In addition, the storage device physically erases the stored write data upon receiving a selective purge request from the host device.

Claim (Index 11):
A method of operating a storage system, the method comprising:\n receiving a first packet which is based on a write command, a logical address of write data corresponding to the write command, and a selective purge tag indicating that the write data are targeted for selective purge, wherein the first packet is generated by a host device receiving a second packet which is based on the write data, wherein the second packet is generated by the host device; parsing the first packet to manage the logical address in a selective purge group; storing the write data from the second packet; logically erasing the stored write data from a storage device based on an erase command received from the host device; and physically erasing the stored write data from the storage device based on a third packet corresponding to a selective purge request from the host device.
