  • Patent number: 12650899
    Abstract: Apparatuses and methods for error correction based on data characteristics are disclosed. Data characteristics can include importance of the data. Data is received at a memory controller from a host device, and a characteristic of the received data is determined. A level of error correction is selected from a plurality of error correction levels for the received data based on the determined characteristic. The received data and an error correction code are written to a memory. The error correction code is generated based on the selected level of error correction. In some implementations, the characteristic of the received data is determined using a neural network.

  • Publication number: 20260119605
    Abstract: The disclosure is directed toward a method to efficiently perform a large language model operation by reducing the memory and computation resources for operating on a matrix such as a weight matrix. The weight matrix may be included in operations such as the head attention function of the large language model. The weight matrix is decomposed into multiple submatrices that each include a set of weights from the weight matrix. An input of the large language model is provided. A submatrix solution for the submatrix is determined from the input and the set of weights of the submatrix. The determining of a solution is repeated for each of the submatrices to provide multiple submatrix solutions. The resulting submatrix solutions are combined to obtain a matrix solution for the weight matrix.

  • Publication number: 20260050391
    Abstract: The present invention relates to a memory controller and a memory device that are configured to communicate with each other using multiple input multiple output (MIMO) technology. The memory controller includes a precoder that precodes data for transmission. The precoding is based on channel state information, a neural network, or both. The memory device receives the precoded data and decodes them to retrieve the original data. In some cases, the precoder uses the channel state information to optimize the precoding matrix for the given channel conditions. In some cases, a neural network is trained to predict the optimal precoding matrix for the current channel state. The precoding matrix is then used to encode the data, which is then transmitted to the memory device. The use of MIMO and precoding improves the reliability and efficiency of the communication between the memory controller and memory device.

  • Publication number: 20250315502
    Abstract: Methods and apparatus for performing diversity matrix operations within a memory fabric and for converting a memory array into a matrix fabric for spatial diversity-related matrix transformations and performing matrix operations therein. Exemplary embodiments described herein perform MIMO-related matrix transformations (e.g., precoding, beamforming, or data recovery matrix operations) within a memory device that includes a matrix fabric and matrix multiplication unit (MMU). In one variant, the matrix fabric uses a “crossbar” construction of resistive elements. Each resistive element stores a level of impedance that represents the corresponding matrix coefficient value. The crossbar connectivity can be driven with an electrical signal representing the input vector as an analog voltage. The resulting signals can be converted from analog voltages to a digital values by an MMU to yield a matrix-vector product. The MMU may additionally perform various other logical operations within the digital domain.
