    Abstract: A semiconductor device can include a substrate of semiconductor material and multiple stacks of memory cells disposed within the substrate. Each of the stacks can include a conductive string that connects memory cells to a bitline where each memory cell is located at an intersection of the conductive string and a wordline. The device can also include capacitor having a cylindrical body disposed between two adjacent stacks of memory cells where the capacitor includes an inner conductive layer and an outer conductive layer at least partially surrounding the inner conductive layer, where the inner conductive layer and the outer conductive layer are separated by a dielectric layer. The device can further include a power supply line conductively connected to an end of the capacitor at a base of the cylindrical body.

    Abstract: A processing device, operatively coupled with a memory device, performs a first programming operation on a first set of cells associated with a first sub-block of a first die of the memory device, wherein each die of the memory device comprises a plurality of sub-blocks. The processing device identifies, based on a first predefined value, a second sub-block of a second die of the memory device on which to perform a second programming operation, wherein the first predefined value is a shift in an index value of the first sub-block of the first die of the memory device. The processing device further performs the second programming operation on a second set of cells associated with the second sub-block of the second die, wherein the second sub-block of the second die is associated with a different index value than the first sub-block of the first die.

    Abstract: A request to perform a program operation on a set of vertically stacked memory cells of a memory device is received. A sensing time adjustment value based on a number of program erase cycles (PECs) associated with the memory device is determined responsive to determining that at least one memory cell of the set of vertically stacked memory cells is non-programmable. A default sensing time is adjusted by the sensing time adjustment value to generate an adjusted sensing time. The program operation on the set of vertically stacked memory cells is performed using the adjusted sensing time.
