  • Patent number: 11469777
    Abstract: The present disclosure provides a method for optimizing a protograph-based LDPC code over an underwater acoustic (UAW) channel. The traditional protograph-based LDPC code over an UAW channel does not consider performance in an error floor region. The method first determines parameters such as a protograph-based LDPC code length, a basic protograph, a target decoding threshold, a threshold adjustment factor, and an ACE check parameter. The protograph is optimized, and the method constructs a parity check matrix by using a UAW channel-based PEG/ACE hybrid algorithm, performs ACE check on the parity check matrix, and calculates a decoding threshold for the matrix passing the check. If the decoding threshold is within a range of an iterative decoding threshold, the parity check matrix is a final optimized matrix. Otherwise, the method continues to optimize the protograph until a parity check matrix passing the check is obtained.

    Abstract: Read error mitigation in solid-state memory devices. A solid-state drive (SSD) includes a read error mitigation module that monitors one or more memory regions. In response to detecting uncorrectable read errors, memory regions of the memory device may be identified and preemptively retired. Example approaches include identifying a memory region as being suspect such that upon repeated read failures within the memory region, the memory region is retired. Moreover, memory regions may be compared to peer memory regions to determine when to retire a memory region. The read error mitigation module may trigger a test procedure on a memory region to detect the susceptibility of a memory region to read error failures. By detecting read error failures and retirement of a memory regions, data loss and/or data recovery processes may be limited to improve drive performance and reliability.

  • Patent number: 11202085
    Abstract: Innovations in hash table construction and hash-based block matching for image encoding or video encoding are described. For example, an encoder determines hash values for base-size candidate blocks in a reference picture. The encoder stores, in a hash table, the hash values for the base-size candidate blocks. The encoder encodes a trial-size current block in a current picture. In some cases, the trial-size current block has a block size larger than the base block size. As part of the encoding, the encoder uses hash-based block matching, between base-size current blocks of the trial-size current block and the base-size candidate blocks, to identify a trial-size matching block, if any, in the reference picture. The encoder stores hash values only for the base-size candidate blocks. This can significantly reduce the computational cost and memory cost for hash table construction during encoding, without hurting compression efficiency or the overall speed of encoding.

  • Patent number: 11139026
    Abstract: A variable reference based sensing scheme is described. In one example, performance of a memory command to access a crosspoint memory device such as a memory read or memory write command involves a sensing operation. In one example, a memory read operation involves applying a voltage across the memory cell and sensing current through the cell. The current through the memory cell is compared with one of multiple reference currents to determine the state of the memory cell. The reference current is selected based on the voltage applied across the memory for the sensing operation. Different reference currents may be used for different types of operations. For example, different reference currents may be selected for a write sensing operation than for a read sensing operation.

  • Patent number: 11126498
    Abstract: Methods, systems, and apparatus to selectively implement single-error correcting (SEC) operations or single-error correcting and double-error detecting (SECDED) operations, without noticeably impacting die size, for information received from a host device. For example, a host device may indicate that a memory system is to implement SECDED operations using one or more communications (e.g., messages). In another example, the memory system may be hardwired to perform SECDED for certain options. The memory system may adapt circuitry associated with SEC operations to implement SECDED operations without noticeably impacting die size. To implement SECDED operations using SEC circuitry, the memory system may include some additional circuitry to repurpose the SEC circuitry for SECDED operations.

  • Patent number: 11038537
    Abstract: Disclosed herein are example embodiments of protocols to distill magic states for T-gates. Particular examples have low space overhead and use an asymptotically optimal number of input magic states to achieve a given target error. The space overhead, defined as the ratio between the physical qubits to the number of output magic states, is asymptotically constant, while both the number of input magic states used per output state and the T-gate depth of the circuit scale linearly in the logarithm of the target error. Unlike other distillation protocols, examples of the disclosed protocol achieve this performance without concatenation and the input magic states are injected at various steps in the circuit rather than all at the start of the circuit. Embodiments of the protocol can be modified to distill magic states for other gates at the third level of the Clifford hierarchy, with the same asymptotic performance.

  • Patent number: 11016703
    Abstract: A delay due to retry processing with regard to occurrence of a memory write error is suppressed. A sub-region command holding section holds a host command as a sub-region command divided with respect to each access target sub-region. A sub-region address conversion section converts an address of an access target sub-region to an address of a memory regarding a sub-region command. A sub-region command execution section executes a sub-region command whose address has been converted, and accesses a memory. In a case where a write error occurs in a memory regarding a sub-region command, an address conversion management section performs preparation processing of a substitute region for a sub-region command in which the write error has occurred concurrently with execution of another sub-region command in the sub-region command execution section.

  • Patent number: 10956338
    Abstract: A technique for improving performance of a cache is provided. The technique involves maintaining indicators of whether cache entries are dirty in a random access memory (“RAM”) that has a lower latency to a cache controller than the cache memory that stores the cache entries. When a request to invalidate one or more cache entries is received by the cache controller, the cache controller checks the RAM to determine whether any cache entries are dirty and thus should be written out to a backing store. Using the RAM removes the need to check the actual cache memory for whether cache entries are dirty, which reduces the latency associated with performing such checks and thus with performing cache invalidations.
