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.

Abstract: A memory system includes a storage device including a turbo write buffer and a user storage area implemented with a nonvolatile memory, and a host configured to transfer a read request to the storage device. In response to the read request, the storage device transfers read data and read data information including attributes of the read data to the host.

Abstract: A storage system shares a system memory of a host. An operation method of the storage system may include receiving a command including information about a shared memory from the host, receiving a stream command having no timeout from the host, and transmitting a first packet associated with the stream command to the host in response to the received stream command. The first packet includes information for accessing the shared memory.

Abstract: A storage device includes a nonvolatile memory device that includes a first region including memory cells configured to store n-bit data and a second region including memory cells configured to store m-bit data and a memory controller, where n and m are natural numbers and n is less than m. The first region includes a first area and a second area, and the second region includes a third area. The memory controller is configured to perform one of a turbo write operation on the first area or the second area and a normal write operation on the third area, and configured to perform one of a turbo read operation on the first area or the second area and a normal read operation on the third area.
