  • Patent number: 12657448
    Abstract: A neuromorphic architecture is formed from a laminate of non-woven carbon fiber reinforced polymer layers arranged in a plurality of different directions. A plurality of distributed nodes are formed through the laminate via transverse voids, and an encapsulant encapsulates an electrochemical fluid or gel such that the electrochemical fluid or gel may flow within the nodes and around the laminate. Electrical current flowing through the architecture creates reversible metal deposits at various nodes, depending on the path developed through the architecture, with a complexity sufficient for neuromorphic processing, and providing a writable and erasable memory. A neuromorphic actuator may be formed by combining shape memory materials with such a neuromorphic architecture, which may provide desired surface contours and/or actuations based on current in the neuromorphic architecture.

  • Patent number: 12658223
    Abstract: To reduce power consumption and circuitry requirements, the following presents an “unmatched” data output architecture, in which the clock path does not mimic the data path. To provide proper data transfers in the data output path, the clock signal is tuned at points of the clock path, such as for data transfers from internal data buses to FIFOs and from the FIFO though the multiplexers to the input/output pads. An amount of timing offset is introduced in the generation of internal transfer clocks, which can be determined as part of a valid data window training process that can be performed by the controller, such as part of the power up process.

  • Patent number: 12651639
    Abstract: Memory devices, systems including memory devices, and methods of operating memory devices are described, in which memory device are configured to add variable delays to a command. The variable delays may be provided by a host device (e.g., a test equipment) using a test mode of the memory devices. Alternatively, the variable delays may be stored in nonvolatile memory (NVM) components of the memory devices. Further, mode registers of the memory devices may be set to indicate that the command is associated with the variable delays stored in the NVM components. Further, the memory devices may include delay components configured to add the variable delays to the command. Such variable delays facilitate staggered execution of the command across multiple memory devices so as to avoid (or mitigate) issues related to an instantaneous, large amount of current drawn from a power supply connected to the memory devices.

    Abstract: The memory array of a circuit includes sub-arrays with memory cells arranged in a row-column matrix where each row includes a word line and each sub-array column includes a local bit line. A control circuit supports two modes of circuit operation: a first mode where only one word line in the memory array is actuated during a memory read and a second mode where one word line per sub-array are simultaneously actuated during the memory read. An input/output circuit for each column includes inputs to the local bit lines of the sub-arrays, a column data output coupled to the bit line inputs, and a sub-array data output coupled to each bit line input. In memory computation operations are performed in the second mode as a function of feature data and weight data stored in the memory.

  • Patent number: 12603139
    Abstract: When performing a read process, a non-volatile memory first performs a pre-read sensing of the condition of memory cells connected to neighbor word lines. While applying a first word line voltage associated with a first programmed data state to the selected word line, the memory system performs two sensing operations for the first programmed data state on selected memory cells that have neighbor memory cells on the neighbor word lines in a first condition and perform two sensing operations for the first programmed data state on selected memory cells that have neighbor memory cells on the neighbor word lines in a second condition. Based on that sensing, the data being stored in the set of selected memory cells is determined. In some embodiments, at least one of the two sensing operations for each condition includes sensing soft bit information that improves the data decoding process.

  • Patent number: 12592291
    Abstract: A non-volatile memory attempts to read a data set from a plurality of non-volatile memory cells in multiple threshold voltages distributions and determines that the data set was not read successfully due to there being too many errors in the data read. In response to determining that the data set was not read successfully, the system identifies memory cells storing error bits that are in upper tails and lower tails of the threshold voltages distributions. To reduce the number of errors, memory cells storing error bits that are in upper tails have their threshold voltages reduced by bit level erase and memory cells storing error bits that are in lower tails their threshold voltages increased to move the memory cells closer to the center of their respective threshold voltages distributions by bit level program.
