Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

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 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.
