Abstract: Methods of operating a memory, and memory configured to perform similar methods, might include applying a positive first voltage level to a first node selectively connected to a string of series-connected memory cells while applying a negative second voltage level to a control gate of a transistor connected between the first node and the string of series-connected memory cells, and increasing the voltage level applied to the first node to a third voltage level while increasing the voltage level applied to the control gate of the transistor to a fourth voltage level lower than the third voltage level and higher than the first voltage level.

Abstract: Exemplary methods, apparatuses, and systems include an adaptive pre-read manager for controlling pre-reads of the memory device. The adaptive pre-read manager receives a first set of data bits for programming to memory. The adaptive pre-read manager performing a first pass of programming including a first subset of data bits from the set of data bits. The adaptive pre-read manager compares a set of threshold operating differences to a set of differences between multiple operating conditions during the first pass of programming and current operating conditions. The adaptive pre-read manager performs an internal pre-read of the programmed first subset of data bits. The adaptive pre-read manager performs a second pass of programming using the internal pre-read and a second subset of data bits from the first set of data bits.

Abstract: A transistor comprises a channel region having a frontside and a backside. A gate is adjacent the frontside of the channel region with a gate insulator being between the gate and the channel region. Insulating material having net negative charge is adjacent the backside of the channel region. The insulating material comprises at least one of AlxFy, HfAlxFy, AlOxNy, and HfAlxOyNz, where “x”, “y”, and “z” are each greater than zero. Other embodiments and aspects are disclosed.

Abstract: A memory device includes a memory array and control logic to perform operations including identifying a target cell and a set of cells adjacent to the target cell. Each cell of the set of cells is associated with a respective adjacent cell state. The operations further include determining, for each adjacent cell state, a respective interference value, assigning, based on the respective interference value, each adjacent cell state to a respective bin of a set of state information bins, and in response to determining that each bin of the set of state information bins has at least one adjacent cell state assigned to it, and determining a set of read level offsets for reading the target cell. Each read level offset of the set of read level offsets is associated with a respective bin of the set of state information bins.

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.

Abstract: A memory access operation is initiated to read a set of target memory cells of a target wordline of the memory device. During the memory access operation, a read voltage level is caused to be applied to the target wordline. During the memory access operation, a first pass through voltage level is caused to be applied to a first wordline adjacent to the target wordline. During the memory access operation, a second pass through voltage is caused to be applied to a second wordline adjacent to the target wordline, wherein the first pass through voltage level is less than the second pass through voltage level.
