Method of operating storage device, storage device performing the same and method of operating storage system using the same

A universal flash storage (UFS) device, comprising:

• a plurality of nonvolatile memories;
• and
• a controller configured to control the plurality of nonvolatile memories, to receive a first command from a host device, to receive entry information corresponding to the first command, from the host device, to receive a second command corresponding to the first command, and to perform a data read operation based on the second command and the entry information,
• wherein a field of the first command comprises a logical block address information that indicates at least one logical block address for the data read operation, and a host performance booster (HPB) prefetch identification (ID),
• wherein a field of the second command comprises a read ID, a logical block address information, and a part of the entry information,
• wherein the read ID identifies a relationship between the first command and the second command, and
• wherein the entry information indicates at least one physical address for performing the data read operation.

A storage system, comprising:

• a universal flash storage (UFS) device;
• and
• a host device configured to control the UFS device, to transmit a first command to the UFS device, to transmit entry information corresponding to the first command to the UFS device, and to transmit a second command corresponding to the first command to the UFS device,
• wherein the UFS device is configured to perform a data read operation based on the second command and the entry information,
• wherein a field of the first command comprises a logical block address information that indicates at least one logical block address for a data read operation, and a host performance booster (HPB) prefetch identification (ID),
• wherein a field of the second command comprises a read ID, a logical block address information, and a part of the entry information,
• wherein the read ID identifies a relationship between the first command and the second command, and
• wherein the entry information comprises information indicating at least one physical address for performing the data read operation.
