1. A method for performing save state switching in selective lanes between a first electronic device and a second electronic device in a Universal Flash Storage UFS system, the method comprising:
determining, by the first electronic device, whether a data request is directly received from an application layer of the first electronic device;
performing, by the first electronic device, at least one of:
setting a first lane from among a plurality of lanes between the first electronic device and the second electronic device 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 between the first electronic device and the second electronic device to the active state based on determining that the data request is received from the application layer of the first electronic device,
based on the setting the first lane to the active state, transmitting, by the first electronic device, 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.
