    Abstract: A Peripheral Component Interconnect Express (PCIe) system and method achieve reduced latency and improved performance by reconfiguring the PCIe link to use an increased number of lanes for retransmitting data packets held in a replay buffer if one or more data packets transmitted by the TX device are flagged as not acknowledged (NACK) by the RX device. Before retransmitting the NACK-flagged packet(s), the link is reconfigured to use a greater number of lanes, preferably the maximum number of lanes that are available for use, and then the NACK-flagged packet(s) is retransmitted using the greater number of lanes until successful receipt of the NACK-flagged packets has been acknowledged by the RX device. Once the NACK-flagged packet(s) is successfully received by the RX device, the link is reconfigured to use the previous number of lanes and operations of the link resume using the previous number of lanes.

    Abstract: In some aspects, the present disclosure provides a method for managing a command queue in a universal flash storage (UFS) host device. The method includes receiving, by a host controller, a plurality of memory commands from a UFS driver, storing, by the host controller, the plurality of memory commands in a command queue, and determining, by the host controller, whether the plurality of memory commands comprises a contiguous set of commands, where a number of the contiguous set of commands is greater than a threshold number of commands, and where each command of the contiguous set of commands has a priority less than a threshold priority.

    Abstract: In some aspects, the present disclosure provides a method for managing memory commands from a plurality of masters. The method includes receiving, at a storage driver, a plurality of memory commands from the plurality of masters and determining, by the storage driver, a number of command queues of a plurality of command queues to use to service the plurality of memory commands. In certain aspects, the method includes routing, via one or more of a plurality of lanes, the plurality of memory commands to a storage controller according to the determined number of command queues, wherein each of the plurality of lanes corresponds to one of the plurality of command queues and storing, by the storage controller, one or more of the plurality of memory commands in each of the determined number of command queues.
