Classification: CPC G  H  Y | IPC G

Claim 5:
6. A Universal Flash Storage (UFS) system for performing save state switching using selective lanes, the UFS system comprising:
a first electronic device; and
a second electronic device communicatively coupled to the first electronic device using a plurality of lanes,
wherein the first electronic device comprises:
a UFS memory configured to support one or more power save states, and a lane controller configured to:
determine whether a data request is directly received from an application layer of the first electronic device; and
perform at least one of:
setting a first lane from among the plurality of lanes to an active state and the other lanes from among the plurality of lanes to a power save state based on determining that the data request is not received from the application layer of the first electronic device; and
setting the plurality of lanes to the active state based on determining that the data request is received from the application layer of the first electronic device,
wherein the lane controller is further configured to perform:
based on the setting the first lane to the active state, transmitting at least one of an Acknowledgement and Flow Control (AFC) frame and credit information corresponding to data, from the first electronic device, to the second electronic device using the first lane; and

based on the setting the plurality lanes to the active state, transmitting data from the first electronic device to the second electronic device using at least one lane from among the plurality of lanes.
