Abstract: A storage device including: a nonvolatile memory device including a first, second and third area; and a controller to receive a first write command including a first logical block address from a host, to receive first data corresponding to the first logical block address in response to the first write command, and store the first data in the nonvolatile memory device, when the first write command includes area information, the controller stores the first data in the first area or the second area based on the area information, when the first write command does not include the area information, the controller stores the first data. in the third area, each of the first area and the second area includes memory cells each storing “n” bits (n being a positive integer), and the third area includes memory cells each storing “m” bits (m being a positive integer greater than n).

Abstract: A storage device including a nonvolatile memory device is described. The storage device includes a controller that receives a write command and data from an external host device. The controller preferentially writes the data in an area based on a normal write policy when the data is associated with a normal write, and in an area based on a turbo write policy when the data is associated with a turbo write. The controller may also receive a read command, to read data from an area based on the read command, and output the data to the external host device. The controller may also move the data in response to move information of the read command when the read command is received together with move information.

Abstract: Provided is a semiconductor device and a semiconductor system. A semiconductor device can include a command priority policy manager circuit which generates command priority policy information including a command priority compliance policy for a command directed to a device. A host interface circuit can be coupled to the command priority policy manager circuit to receive the command priority policy information from the command priority policy manager circuit, where the host interface circuit operable to transmit the command priority policy information via an electrical interface to the device.

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 method includes transmitting a command signal including a time-out time from a host to a storage device; determining, by the storage device, a first time amount, which is an amount of time required for the storage device to perform an operation corresponding to the command signal; when the first time amount is not greater than the time-out time, providing a first response signal including a success flag from the storage device to the host after the storage device performs the operation within the time-out time; when the first time amount is longer than the time-out time, providing a second response signal including the first time amount and a time-out reset flag from the storage device to the host; and when the host receives the second response signal, retransmitting the command signal to the storage device after the host resets the time-out time to the first time amount.
