A method and an initiator device for autonomous detection of status of a link between the initiator device and a target device in a Universal Flash Storage (UFS) system. The method includes determining whether an Acknowledgement and Flow Control (AFC) frame for a data frame is received before expiry of a turn-around timer. If the AFC frame is received from the target device before expiry of the turn-around timer, then the method detects the status of the link between the initiator device and the target device as active. If the AFC frame is not received from the target device before expiry of the turn-around timer then, the method detects the status of the link between the initiator device and the target device by restarting the turn-around timer with a second time period.

Autonomous detection of status of link between initiator device and target device in UFS system

Disclosed are a method and a Universal Flash Storage (UFS) system for performing save state switching using selective lanes between a first electronic device and a second electronic device. The method includes: determining, by the first electronic device, whether a data request is received from an application layer of the first electronic device; and 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.

Performing save state switching in selective lanes between electronic devices in UFS system

A method for managing communication between a Universal Flash Storage (UFS) device and a UFS host includes determining at least one path of payload data flow along at least one of a transmission lane of the UFS host and a transmission lane of the UFS device. Based on the determined at least one path of the payload data flow, the method includes initiating, by operating at least one of the UFS host and the UFS device, at least one Hibernate state entry action. Further, the method includes initiating, by operating the at least one of the UFS host and the UFS device, at least one Hibernate state exit action after completion of transfer of a pre-determined number of data frames of the payload data between the UFS host and the UFS device.
