  • Patent number: 12451213
    Abstract: Memory blocks of a metablock are analyzed and tested to determine whether multiple memory blocks fail a first fault assessment. If more than one memory block fails the first fault assessment, the memory blocks are assigned to a retry pool. When in the retry pool, a second fault assessment is performed on the memory blocks. If one or more of the memory blocks pass the second fault assessment, the memory blocks are placed in a memory block pool and are relinked to other memory blocks to form a new metablock. However, if one or more of the memory blocks fail the second fault assessment, the memory blocks are retired.
    Type: Grant

  • Patent number: 11847005
    Abstract: A multiport universal serial bus (USB)-C based power supply device including a USB type-C port configured to supply power to a connected type-C external device, at least one USB type-A port configured to supply power to at least one connected type-A external sink device, a configurable power source and a controller operatively coupled with the configurable power source, the USB type-C port and at least one of the USB type-A port. The controller is configured to generate, based on the generated type-C and type-A power profile, at least one of a digital communication signal and a feedback control signal, which correspond to a power value to be supplied, based on the generated power profile, to the type-C port and the at least one type-A port respectively. Operation of the multiport USB-C based power supply device by a single controller facilitates compact construction of the multiport USB-C based power supply device.
