Publication number: 20250384907Abstract: 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.Type: ApplicationFiled: June 16, 2025Publication date: December 18, 2025Applicant: Micron Technology, Inc.Inventors: Qui Nguyen, Jun Xu, Luyen Vu, Kitae Park, Tomoharu Tanaka, Erwin E Yu
