    Abstract: Apparatuses and methods for threshold voltage (Vt) distribution determination are described. A number of apparatuses can include sense circuitry configured to determine a first current on a source line of an array of memory cells, the first current corresponding to a first quantity of memory cells of a group of memory cells that conducts in response to a first sensing voltage applied to an access line and determine a second current on the source line, the second current corresponding to a second quantity of memory cells of the group that conducts in response to a second sensing voltage applied to the access line. The number of apparatuses can include a controller configured to determine at least a portion of a Vt distribution corresponding to the group of memory cells based, at least in part, on the first current and the second current.

    Abstract: Some embodiments include an apparatus having semiconductor pillars in a substantially hexagonally closest packed arrangement. The hexagonally closest packed arrangement includes a repeating pillar pattern which has at least portions of 7 different pillars. Each of the different pillars in a respective one of the repeating pillar patterns is capable of being electrically coupled to a different data line of a plurality of data lines. Some embodiments include an apparatus having semiconductor pillars in a substantially hexagonally closest packed arrangement. The hexagonally closest packed arrangement includes a repeating pillar pattern having at least portions of 7 different pillars. All 7 different pillars of a repeating pillar pattern are encompassed by a single drain-side select gate (SGD).

    Abstract: Systems and methods are disclosed including a memory device and a processing device, operatively coupled with the memory device, to perform operations including programming first data to a set of memory cells of a first wordline using a first number of bits per memory cell. Responsive to receiving second data to program to the set of memory cells of the first wordline, the operations further include determining an error rate associated with a second wordline adjacent to the first wordline. Responsive to determining that the error rate satisfies a threshold criterion, the operations further include selecting a second number of bits per memory cell to program the second data to the first wordline and reprograming, using the second number of bits per memory cell, the first wordline storing the first data by programming second data to the set of memory cells while maintaining the first data.

    Abstract: Methods, systems, and devices for status check using chip enable pin are described. An apparatus may include a memory device, a pin coupled with the memory device, and a driver coupled with the pin and configured to bias the pin to a first a voltage or a second voltage based on a status of the memory device. The status may indicate, for example, whether the memory device is available to receive a command. The driver may bias the pin to a first voltage based on a first status of the memory device indicating that the memory device is busy. Additionally, or alternatively, the driver may bias the pin to a second voltage based on a second status of the memory device indicating that the memory device is available to receive the command. In some cases, the pin may be an example of a chip enable pin.

    Abstract: An example memory sub-system comprises: a memory device; and a processing device, operatively coupled with the memory device. The processing device is configured to: receive a first host data item; store the first host data item in a first page of a first logical unit of a memory device, wherein the first page is associated with a fault tolerant stripe; receive a second host data item; store the second host data item in a second page of the first logical unit of the memory device, wherein the second page is associated with the fault tolerant stripe, and wherein the second page is separated from the first page by one or more wordlines including a dummy wordline storing no host data; and store, in a third page of a second logical unit of the memory device, redundancy metadata associated with the fault tolerant stripe.
