  • Publication number: 20240071510
    Abstract: Exemplary methods, apparatuses, and systems including a programming manager for controlling writing data bits to a memory device. The programming manager receives a first set of data bits for programming to memory. The programming manager writes a first subset of data bits to a first wordline during a first pass of programming. The programming manager writes a second subset of data bits of the first set of data bits to a buffer. The programming manager receives a second set of data bits for programming. The programming manager writes the second subset of data bits of the first set of data bits to the first wordline during a second pass of programming to increase a bit density of memory cells in the first wordline in response to receiving the second set of data bits.
