Abstract
A method of operating a storage device includes receiving, from a host, a first packet containing a buffer address indicating a location of a data buffer selected from among a plurality of data buffers in the host, parsing the buffer address from the first packet, and transmitting a second packet containing the buffer address to the host in response to the first packet.
Claims20
A storage device comprising:
- a nonvolatile memory;
- and
- a controller coupled to the nonvolatile memory, wherein the controller is configured to:
- receive a first command and a first address from an external device,
- transmit first data corresponding to the first command and the first address to the external device,
- receive a second command and a second address from the external device, and
- transmit the second address and a request for second data corresponding to the second command to the external device.

A storage device comprising:
- a nonvolatile memory;
- and
- a controller coupled to the nonvolatile memory, wherein the controller is configured to:
- receive a first packet including a read command and a first address from an external device,
- read first data stored in the nonvolatile memory, and
- transmit a second packet including the first address and the first data corresponding to the read command to the external device,
- wherein the controller communicates with the external device via a universal flash storage (UFS) interface, and
- each of the first packet and the second packet is a UFS protocol information unit (UPIU).
5 more elements
A storage device comprising:
- a nonvolatile memory;
- and
- a controller coupled to the nonvolatile memory, wherein the controller is configured to:
- receive a first packet including a write command and a first address from an external device, and
- transmit a second packet including the first address and a request for first data corresponding to the write command to the external device,
- wherein the controller communicates with the external device via a universal flash storage (UFS) interface, and wherein
- each of the first packet and the second packet is a UFS protocol information unit (UPIU).
