Techniques for fast copy in universal flash storage (UFS) devices

Abstract

Example implementations include a methods and apparatuses for fast copy at a universal flash storage (UFS) device. The UFS device may transmit, to a host device, a fast copy only (FCO) capability message that includes one of a first indication that signifies support for fast copy operations or a second indication that signifies no support for fast copy operations. The UFS device may further receive, from the host device, an extended copy command for one of a device-based fast copy control operation or a logical unit-based control operation. The UFS device may further perform one of the device-based fast copy control operation or the logical unit-based fast copy control operation based on receiving the extended copy command.
