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.

Storage device, memory system comprising the same, and operation method thereof

A storage device that includes a nonvolatile memory device is described. The storage device includes areas and a controller. The controller receives a write command and data from an external host device. The controller then preferentially writes the data in an area associated with a turbo write based on a turbo write policy, or in an area not associated with a turbo write based on a normal write policy. The controller also receives a move command from the external host device and moves data stored in the area to a different area based on the move command.

Storage device and method for accelerating storage device write and read speed using a turbo-write buffer

A memory device, a host device and a memory system are provided. The memory device may include a plurality of storage units configured to store data, and at least one device controller configured to, receive a read command from at least one host device and to read data stored in the plurality of storage units in response to the read command, the at least one host device including at least one host memory including a plurality of HPB (high performance boosting) entry storage regions, and provide the at least one host device with a response command, the response command indicating an activation or deactivation of the plurality of HPB entry storage regions, the response command including HPB entry type information which indicates a HPB entry type of the HPB entry storage region.

Memory device, host device and memory system comprising the memory device and host device

An operation method of a UFS device including: determining, by a host, area information for write data, wherein in a turbo read the write data is stored in a non-pinned or pinned buffer area and in a normal read the write data is stored in a user storage; transferring, by the host, a first command UFS protocol information unit (UPIU); transferring, by the UFS device, an RTT UPIU to the host, transferring, by the host, a DATA OUT UPIU to the UFS device; mapping, by UFS device, a first logical block address with a physical address of an area corresponding to the area information; transferring, by the host, a second command UPIU; and performing the turbo read on the area to read data corresponding to the first logical block address when the area corresponding to the area information is the pinned or non-pinned turbo write buffer.

Storage device including a turbo write buffer divided into a non-pinned buffer area and a pinned buffer area, an operation method of a storage system including the storage device in which data of the non-pinned and pinned buffer areas are flushed differently, and a host device controlling the storage device

A memory system includes a host device including a host controller, and a memory device including a device controller and a non-volatile storage including a purge region and a memory region. The device controller communicates purge information associated with the purge region and including size information of the purge region. The host controller communicates a request for generating a first partition for a first logical unit in the memory region, and communicates a request for generating a second partition for a second logical unit in the purge region in response to the size information of the purge region.

Method of operating memory device and host device, and memory system including partitioning purge region responsive to purge information

A storage device includes a descramble module configured to descramble at least a portion of a read command, which includes logical block address (LBA) information and first meta information, into first signature information and first physical address (PA) information, for accessing a flash memory. A compare module is provided, which is configured to compare the first signature information against stored signature information to thereby determine an equivalency or discrepancy therebetween. An access module is provided, which is configured to use the first PA information to access a data region of the flash memory, upon determination of the equivalency by said compare module.

Storage devices that support cached physical address verification and methods of operating same

Provided is a storage device which communicates with a host device and configured to set a secure mode of a plurality of commands different in kind. An operating method of the storage device includes receiving a secure request indicating a protection of a first command and a protection of a second command of the plurality of commands, from the host device; setting a secure mode of the first and second commands, based on the secure request; receiving a first request indicating a request to execute the first command, from the host device; outputting a first response indicating failure of the first command to the host device, based on the first request; receiving a second request indicating a request to execute the second command, from the host device; and outputting a second response indicating failure of the second command to the host device, based on the second request.

Operating method of storage device setting secure mode of command, and operating method of storage system including the storage device

Provided are an operating method of a host device, an operating method of a memory device, and a memory system. The operating method of a host device includes transmitting a request command for performing an eye-opening monitor (EOM) operation to a memory device, transmitting a parameter for performing the EOM operation to the memory device, transmitting pattern data for performing the EOM operation to the memory device, and receiving a first response signal including a result of the EOM operation performed based on the parameter and the pattern data from the memory device.

Operating method of host device and memory device and memory system

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.
