    Abstract: Some embodiments include an assembly having a stack of alternating dielectric levels and conductive levels. Channel material pillars extend through the stack. Some of the channel material pillars are associated with a first sub-block, and others of the channel material pillars are associated with a second sub-block. Memory cells are along the channel material pillars. An insulative level is over the stack. A select gate configuration is over the insulative level. The select gate configuration includes a first conductive gate structure associated with the first sub-block, and includes a second conductive gate structure associated with the second sub-block. The first and second conductive gate structures are laterally spaced from one another by an intervening insulative region. The first and second conductive gate structures have vertically-spaced conductive regions, and have vertically-extending conductive structures which electrically couple the vertically-spaced conductive regions to one another.

    Abstract: Methods, apparatuses, and systems for tensor memory access are described. Multiple data located in different physical addresses of memory may be concurrently read or written by, for example, employing various processing patterns of tensor or matrix related computations. A memory controller, which may comprise a data address generator, may be configured to generate a sequence of memory addresses for a memory access operation based on a starting address and a dimension of a tensor or matrix. At least one dimension of a tensor or matrix may correspond to a row, a column, a diagonal, a determinant, or an Nth dimension of the tensor or matrix. The memory controller may also comprise a buffer configured to read and write the data generated from or according to a sequence of memory of addresses.

  • Patent number: 12292831
    Abstract: Methods, systems, and devices for enhanced data reliability in multi-level memory cells are described. For a write operation, a host device may identify a first set of data to be stored by a set of memory cells at a memory device. Based on a quantity of bits within the first set of data being less than a storage capacity of the set of memory cells, the host device may generate a second set of data and transmit a write command including the first and second sets of data to the memory device. For a read operation, the host device may receive a first set of data from the memory device in response to transmitting a read command. The memory device may extract a second set of data from the first set of data and validate a portion of the first set of data using the second set of data.

  • Patent number: 12293101
    Abstract: Methods, systems, and devices for data relocation operation techniques are described. A memory system may include blocks of memory cells, for example, within a non-volatile memory device of the memory system. The memory system may identify a command to perform a data relocation operation associated with a block of memory cells and may select between a first procedure and a second procedure for performing the data relocation operation. The memory system may select between the first procedure and the second procedure based on whether one or more parameters associated with the data relocation operation satisfy a threshold. For example, the memory system may select the first procedure if the one or more parameters satisfy the threshold and may select the second procedure if the one or more parameters do not satisfy the threshold. The memory system may perform the data relocation operation using the selected procedure.

  • Patent number: 12293099
    Abstract: A system includes a memory device and a processing device to initialize a block family associated with the memory device and a timer at initialization of the block family. The processing device further stores, in non-volatile memory of the memory device, a value of the timer before powering down the system while the block family is still open. The processing device further detects a power on of the system and measures a data state metric associated with one or more memory cell of a page of the memory device that is associated with the block family. The processing device further compares a level of the data state metric to a temporal voltage shift function to estimate a time after program value of the page and increments the value of the timer, restored from the non-volatile memory, based on the time after program value.

  • Patent number: 12292795
    Abstract: Methods, systems, and devices for data recovery using ordered data requests are described. In some examples, a memory system receives data units from a host device. A first controller of the memory system generates a protocol unit using the data units. A second controller of the memory system generates a data storage unit using data from the protocol unit, and stores the data unit to a memory device. The memory system performs error detection operations using respective sets of parity bits for each of the units. Upon detecting an error, the memory system, for a write operation, re-requests data associated with error and regenerate the units to correct for the error, or, for a read operation, re-read data associated with the error and regenerate the units to correct for the error.
