  • Publication number: 20250384907
    Abstract: Methods, systems, and devices for techniques for faster sensing operation are provided. In one embodiment, a memory device comprises a data line; a plurality of memory blocks coupled to the data line; and a dedicated memory block coupled to the data line. The dedicated memory block is controllable to generate a sensing current. The memory device further comprises a memory controller configured to, during sensing of a selected memory block of the plurality of memory blocks, cause one or more regulators to: drive the selected memory block such that a pillar current flows through a pillar of the selected memory block, and drive the dedicated memory block to generate the sensing current. The memory device further comprises a sense amplifier configured to sense a data line current. The data line current is a combination of the pillar current and the sensing current.

  • Publication number: 20250356922
    Abstract: Control logic in a memory device causes a pass voltage to be applied to a plurality of wordlines of a block of a memory array of the memory device, the block comprising a plurality of sub-blocks, and the pass voltage to boost a channel potential of each of the plurality of sub-blocks to a boost voltage. The control logic further selectively discharges the boost voltage from one or more of the plurality of sub-blocks according to a data pattern representing a sequence of bits to be programmed to respective memory cells of the plurality of sub-blocks. In addition, the control logic causes a single programming pulse to be applied to a selected wordline of the plurality of wordlines of the block to program the respective memory cells of the plurality of sub-blocks according to the data pattern.

  • Publication number: 20250069683
    Abstract: A memory device includes a memory array includes memory cells grouped into one or more address ranges. Control logic is coupled to the memory array and configured to detect one or more errors associated with one or more stored data items corresponding to a first address range of one or more address ranges. The control logic can determine that a number of the one or more stored data items exceeds a number of redundant memory locations for the first address space. Control logic can remap an association of a first memory address of at least one of the stored data items from a first address within the first address space to a second address in a second address range, where the second address range includes one or more available redundant memory locations.

  • Patent number: 8806155
    Abstract: Memory devices and methods facilitate handling of data received by a memory device through the use of data grouping and assignment of data validity status values to grouped data. For example, data is received and delineated into one or more data groups and a data validity status is associated with each data group. Data groups having a valid status are latched into one or more cache registers for storage in an array of memory cells wherein data groups comprising an invalid status are rejected by the one or more cache registers.
