  • Patent number: 11687281
    Abstract: A memory controller includes a command queue and an arbiter for selecting entries from the command queue for transmission to a DRAM. The arbiter transacts streaks of consecutive read commands and streaks of consecutive write commands. The arbiter transacts a streak for at least a minimum burst length based on a number of commands of a designated type available to be selected by the arbiter. Following the minimum burst length, the arbiter decides to start a new streak of commands of a different type based on a first set of one or more conditions indicating intra-burst efficiency.

  • Patent number: 11635916
    Abstract: Compact representation for input workloads is generated in a memory system, A memory controller includes firmware (FW) and an encoder including recurrent encoding blocks. Each recurrent encoding block receives one of input commands in an input workload, and generates a hidden state vector corresponding to the received input command by applying a set of activation functions on the received input command. The last encoding block generates a final hidden state vector as a compact representation vector corresponding to the input commands. The firmware determines a distance function between the compact representation vector and each of multiple compact workload vectors and tunes at least one of firmware parameters based on the determined distances.

  • Patent number: 11580049
    Abstract: Techniques are described herein for a training procedure that identifies a frame boundary and generates a frame clock to identify the beginning and the end of a frame. After the frame training procedure is complete, a memory device may be configured to execute a frame synchronization procedure to identify the beginning of a frame based on the frame clock without the use of headers or other information within the frame during an active session of the memory device. During an activation time period after a power-up event, the memory device may initiate the frame training procedure. Once the frames are synchronized, the memory device may be configured to use that frame clock during an entire active session (e.g., until a power-down event) to identify the beginning of a frame as part of a frame synchronization procedure.

  • Patent number: 11537326
    Abstract: The present disclosure generally relates to efficiently relocating data within a data storage device. By implementing an error correction code (ECC) module in a complementary metal oxide semiconductor (CMOS) chip for each memory die within a memory array of a memory device, the data can be relocated more efficiently. The ECC decodes the codewords at the memory die. The metadata is then extracted from the decoded codewords and transferred to a controller of the data storage device. A flash translation layer (FTL) module at the controller then checks whether the data is valid by comparing the received metadata to FTL tables. If the metadata indicates the data is valid, then the data is relocated.
