Abstract: In a conventional system with an embedded UFS and an external UFS card are connected to a UFS host, the UFS host is only able to transfer data to the embedded UFS or to the an external UFS card, but not to both at the same time. To address this issue, it is proposed to provide a host that is capable of concurrently transferring data to multiple storage devices.

Abstract: Methods that may be performed by a universal flash storage (UFS) system of a computing device for updating logical-to-physical (L2P) address mapping tables. Various embodiments may include enabling a device control mode (DCM) of host performance booster (HPB) based on a flush of a writebooster buffer to a normal storage of a UFS device of the UFS system, and updating an L2P address mapping table at a host device of the UFS system while DCM is enabled based on the flush of the writebooster buffer to the normal storage. Some embodiments may include generating a signal having an indicator of a UFS protocol information unit configured to indicate a change in an HPB mode at the UFS device based on the flush of the writebooster buffer to the normal storage, and sending the signal from the UFS device to the host device.

Abstract: In some aspects, the present disclosure provides a method for managing data communication rates of a memory device. The method includes receiving an input/output (I/O) operation to be performed by the memory device, detecting a temperature of the memory device, and determining whether the detected temperature satisfies a threshold condition. The threshold condition is satisfied if the detected temperature is above a first temperature threshold or below a second temperature threshold. If the threshold condition is satisfied, selecting a gear from a plurality of gears based on a ranking of the plurality of gears at the detected temperature, wherein each gear of the plurality of gears correspond to a respective one of a plurality of data rates used by the memory device for performing I/O operations, and serving, to the memory device, the I/O operation with an indication to perform the I/O operation using the selected gear.

Abstract: A Peripheral Component Interconnect Express (PCIe) system and method achieve reduced power consumption and latency. When the link transitions from an active functional state in which the link has a first configuration of N active lanes to a power-saving state, the number of active lanes is collapsed such that M of the N lanes are maintained in an active power-saving state and P of the N lanes are maintained in an electrically idle state, where M, N and P are positive integers and N>P>M. The reduction in lane width reduces power consumption. Bit values specifying the current link configuration can be saved in a control register and read and compared to bit values contained in a link control register before transitioning back to the active functional state. If the bit values match, the active functional state is resumed directly from the recovery state, thereby reducing latency.

Abstract: Methods that may be performed by a host controller of a computing device for synchronizing logical-to-physical (L2P) tables before entering a hibernate mode are disclosed. Embodiment methods may include determining whether a first L2P table stored in a dynamic random-access memory (DRAM) communicatively connected to the host controller is out of synchronization with a second L2P table stored in a static random-access memory (SRAM) of a universal flash storage (UFS) device communicatively connected to the host controller via a link. If the first and second L2P tables are out of synch, the host controller may retrieve at least one modified L2P map entry from the second L2P table when the UFS device is configured to enter a hibernate mode from the UFS device, and update the first L2P tabled with the at least one modified L2P map entry before the link and the UFS device enter the hibernate mode.

Abstract: Certain aspects of the present disclosure provide techniques for performing face recognition in low light conditions using an electronic device. One aspect provides a method including determining if a brightness level within a viewing area of the electronic device satisfies a threshold. The method includes increasing a luminance output of the electronic device from a first luminance level to a second luminance level when the brightness level does not satisfy the threshold. The method includes capturing an image at the second luminance level when the brightness level does not satisfy the threshold. The method includes capturing the image at the first luminance level when the brightness level satisfies the threshold. The method includes detecting a face in the image. The method includes determining if the face corresponds to an authorized user. The method includes unlocking the electronic device when the face corresponds to an authorized user.

Abstract: In a conventional system with a UFS storage device connected to a UFS host over one or more lanes, the lanes can support different transmission speeds, referred to as gears. The UFS host shifts lanes and gears based on the type of request it receives. When the requests arrive in random order of gear requirements, the frequent shifting of the lanes and gears causes significant power consumption. To address this issue, it is proposed to implement a queue-based shifting in which arriving requests may be queued based on their gear requirements. When a queue is selected, multiple requests in the selected queue, which are all of same or similar gear requirement, can be served. This can reduce the frequency of gear shifting, and hence reduce power consumption.

Abstract: A host device includes a memory configured to store a logical-to-physical address mapping table of a flash memory device. The host device also includes one or more processors coupled to the memory and configured to be coupled to the flash memory device. The one or more processors are configured to determine whether a trigger condition is satisfied. The trigger condition is associated with checking a distribution of write data that is written to the flash memory device. The one or more processors are also configured to, based on a determination that the trigger condition is satisfied, identify a die of the flash memory device that has a higher data occupancy than at least one other die of the flash memory device, and send a command to the flash memory device to move data from the identified die to one or more other dies of the flash memory device.

Abstract: A system and method reduce bootup latency in systems that run Auto operating systems (Auto OS). When, or just prior to, the system controller initiating suspend-to-disk (S2D) process entry, the system controller causes a memory controller to determine the percentage of volatile memory that is currently occupied and compares that percentage of occupancy to a predetermined threshold (TH) percentage. If the percentage of occupancy exceeds the predetermined TH percentage, then the memory controller tags apps that are occupying volatile memory as either background apps or foreground apps, terminates the background apps, clears volatile memory of any instructions and data associated with the terminated background apps, takes a snapshot of the state of volatile memory after the terminated background apps and associated data have been cleared, and saves the snapshot to a designated storage location in nonvolatile memory before entering hibernate mode.
