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 18):
A storage system, comprising:\n a host device configured to generate a command Universal Flash Storage (UFS) protocol information unit (UPIU) including a write command and a selective purge tag indicating that write data corresponding to the write command are targeted for selective purge, and data UPIU including the write data; and a storage device configured to receive the command UPIU and the data UPIU, to manage the write data as a selective purge group, and to logically erase the write data upon receiving an unmap UPIU from the host device, wherein the host device is further configured to: generate a query request UPIU including a selective purge request for physically erasing the write data belonging to the selective purge group, and wherein the storage device is further configured to: receive the query request UPIU; and physically erase the write data belonging to the selective purge group based on the selective purge request.
