  • Publication number: 20240152470
    Abstract: Memory controllers, devices, modules, systems and associated methods are disclosed. In one embodiment, an integrated circuit (IC) memory device is disclosed. The memory device includes an array of storage cells and command interface circuitry to receive an internal transfer command. In response to the internal transfer command, transfer logic reads data from a first portion of the array of storage cells, transfers the data as on-chip transfer data, and writes the on-chip transfer data to a second portion of the array of storage cells. In response to the command interface circuitry receiving an interrupt command, the transfer logic pauses the internal transfer operation, and carries out an unrelated memory access operation involving at least the first portion of the array of storage cells or the second portion of the array of storage cells.

  • Publication number: 20240036975
    Abstract: A memory component internally generates and stores the check bits of error detect and correct code (EDC). In a first mode, during a read transaction, the check bits are sent to the memory controller along with the data on the data mask (DM) signal lines. In a second mode, an unmasked write transaction is defined where the check bits are sent to the memory component on the data mask signal lines. In a third mode, a masked write transaction is defined where at least a portion of the check bits are sent from the memory controller on the data signal lines coincident with an asserted data mask signal line. By sending the check bits along with the data, the EDC code can be used to detect and correct errors that occur between the memory component and the memory controller.

  • Patent number: 11651823
    Abstract: A memory system includes an array of non-volatile memory cells and a memory controller having a first port to receive a program command that addresses a number of the memory cells for a programming operation, having a second port coupled to the memory array via a command pipeline, and configured to create a plurality of fractional program commands in response to the program command. Execution of each fractional program command applies a single program pulse to the addressed memory cells to incrementally program the addressed memory cells with program data, where the duration of the program pulse associated with each fractional program command is a selected fraction of the total programming time typically required to program the memory cells.

  • Publication number: 20220114431
    Abstract: An integrated-circuit neural network includes chain of multiply-accumulate units co-located with a high-bandwidth storage array. Each multiply accumulate includes a digital input port, analog input port and multiply-adder circuitry. The digital input port receives a matrix of digital-weight values from the storage array and the analog input port receives a counterpart matrix of analog input signals, each analog input signal exhibiting a respective electronic current representative of input value. The multiply-adder circuitry generates a matrix of analog output signals by convolving the matrix of digital-weight values with the matrix of analog input signals including, for each analog output signal within the matrix of analog output signals, switchably enabling weighted current contributions to the analog output signal based on logic states of on respective bits of one or more of the digital-weight values.

  • Patent number: 11068388
    Abstract: A method of programming data into a memory device including an array of memory cells is disclosed. The method comprises receiving at least one program command that addresses a number of the memory cells for a programming operation to program data in the memory cells. The at least one program command is executed by iteratively carrying out at least one program/verify cycle to incrementally program the addressed memory cells with the program data. A secondary command may be selectively received after initiating but before completing the programming operation. The programming operation may be selectively resumed by first verifying the memory cells, then carrying out at least one program/verify cycle.
