  • Patent number: 11513887
    Abstract: A memory controller includes an interface and a processor. The interface communicates with memory cells that store data in predefined Programming Voltages (PVs).

  • Patent number: 11509428
    Abstract: The present invention discloses a data transmission method having data reuse mechanism that includes the steps outlined below. A driver corresponding to a communication circuit is operated as a transmission terminal to analyze under-transmitted data to generate reuse setting information, indication information and packets having a complete packet and incomplete packets so as to be transmitted by the transmission terminal through a transmission interface to be received by the communication circuit as a receiving terminal. The receiving terminal identifies the complete packet and the incomplete packets according to the indication information. A data location that a reusable data section corresponds to is determined according to the reuse information. The complete packet is outputted. A non-reusable data section of each of the incomplete packets and the reusable data section of the complete packet are reconstructed to output reconstructed packets according to the data location.

  • Patent number: 11500718
    Abstract: A RAID storage controller storage-device-assisted data update system includes a RAID storage controller device coupled to a host system and RAID storage devices in a “look aside” RAID storage controller device configuration. Based on command(s) from the RAID storage controller device, a first RAID primary data storage device may perform a first DMA operation to access first primary data stored on the host system, and write the first primary data to its first buffer subsystem. The first RAID primary data storage device may then perform a first XOR operation using the first primary data stored in its first buffer subsystem and second primary data stored in its first storage subsystem in order to produce first interim parity data, and write the first interim parity data to its second buffer subsystem. The first RAID primary data storage device may then update the second primary data with the first primary data.

  • Patent number: 11496237
    Abstract: A transmission configuration and/or configuration errors and recovery may be determined or implemented by temporal interpretation of one or more signals. A transmitter may interpret one or more signals a first way during one or more time windows and a second way during one or more other time windows. Video resolution may be indicated in a V-by-One® interface by temporal interpretation of HPD and/or CDR lock. Transmission format may be indicated before or after transmission begins. Transmitter configuration error detection and recovery may be implemented by temporal interpretation. A transmitter may transmit data in an assumed/default format. A receiver may indicate the assumed transmission format is incompatible with the receiver configuration. A receiver may indicate a compatible transmission format, for example, based on timing or pulsing transitions in a temporally repurposed signal. A transmitter may respond to the repurposed signal indication by transmitting a different (e.g., compatible) format.

  • Patent number: 11483102
    Abstract: A review and retry mechanism ensures a port channel can be configured to provide and maintain a minimum data speed. A timer-based review sequence reviews the constituent interfaces of a port channel to determine if a minimum speed requirement is met. If the minimum speed cannot be fulfilled, the port-channel member interfaces are un-programmed and removed from the port-channel, rendering the port-channel functionally inactive, thereby preventing network traffic loss. A timer-based retry sequence attempts to program the constituent interfaces. The minimum speed requirement of the interfaces is checked in the next review cycle. If the minimum speed requirement is met, then the review and retry mechanism halts and the port channel continues to remain active; otherwise, the interfaces are un-programmed and the process repeats.

  • Patent number: 11469860
    Abstract: A method reducing amount of memory utilized by hybrid automatic repeat request (HARQ) operations is disclosed. When an apparatus employing the method receives an LDPC encoded packet, the apparatus firstly estimates a signal quality value of the received packet, and performs an LDPC decoding algorithm on the received packet. If the received packet is not successfully decoded by the apparatus, the received and decoding-failed packet is compressed in order to reduce bit-width, and the compressed packet is stored in a memory device for later HARQ operations. The apparatus employing the method is also disclosed.
