    Abstract: Memory devices might include a first latch to store a first data bit; a second latch to store a second data bit; a data line selectively connected to the first latch, the second latch, and a string of series-connected memory cells; and a controller configured to bias the data line during a programing operation of a selected memory cell. The controller may with the first data bit equal to 0 and the second data bit equal to 0, bias the data line to a first voltage level; with the first data bit equal to 1 and the second data bit equal to 0, bias the data line to a second voltage level; with the first data bit equal to 0 and the second data bit equal to 1, bias the data line to a third voltage level; and with the first data bit equal to 1 and the second data bit equal to 1, bias the data line to a fourth voltage level.

    Abstract: Apparatuses and methods for performing buffer operations in memory are provided. An example apparatus can include an array of memory cells, a page buffer, and a controller. The page buffer can be configured to store a number of pages of data in respective caches of the page buffer. The controller can be configured to program the number of pages of data to a first group of cells in the array. The programming operation can include programming the first group of cells to target states encoded with respective data patterns. The programming operation can include incrementally releasing a first of the respective caches of the page buffer responsive to completing programming of cells programmed to a particular first one of the target states.

    Abstract: Apparatuses and methods for an automated dynamic word line start voltage. An example apparatus includes a controller and a memory device. The memory device is configured to maintain, internal to the memory device, a status of a number of open blocks in the memory device. The status can include a programming operation being initiated in the respective number of open blocks. Responsive to receipt of, from the controller, a request to direct initiation of the programming operation to a word line, determine a group of memory cells associated with the word line that programs first relative to other groups of memory cells associated with the word line and maintain, included in the status of an open block, a voltage at which the group of memory cells is the first group to program.

    Abstract: Described are systems and methods for implementing continuous memory programming operations. An example memory device comprises: a memory array comprising a plurality of memory cells electrically coupled to a plurality of conductive lines; and a controller coupled to the memory array. The controller performs operations comprising: performing a memory programming operation with respect to a set of memory cells of the memory array, wherein the memory programming operation comprises a sequence of programming pulses applied to one or more conductive lines electrically coupled to the set of memory cells; responsive to receiving a command to perform a memory access operation, suspending the memory programming operation after performing a current programming pulse of the sequence of programming pulses, wherein the current programming pulse is performed at a first voltage level; initiating the memory access operation; and resuming the memory programming operation by performing a next programming pulse at a second voltage level that exceeds the first voltage level.
