    Abstract: An apparatus that includes a set of memory components of a memory sub-system is provided. The set of memory components include a first memory block comprising first units of linearly arranged memory cells and a second memory block comprising second units of linearly arranged memory cells. The set of memory components include a slit portion dividing the first and second memory blocks. The slit portion includes a capacitor in which a first metal portion of the capacitor is adjacent to the first units of linearly arranged memory cells and a second metal portion of the capacitor is adjacent to the second units of linearly arranged memory cells.

    Abstract: A system can include a memory device and a processing device, operatively coupled with the memory device, to perform operations including writing data to an MU of the memory device and performing one or more scan operations on the MU to determine an aggregate value of a data state metric reflective of an amount of erroneous memory cells in the MU. The operations can include determining whether a value of the data state metric reflective of a specified set of erroneous memory cells in the MU satisfies a criterion and identifying a target programming level to which at least one erroneous memory cell was originally programmed. They can also include reprogramming the at least one erroneous memory cell to the target programming level.

    Abstract: A method for using and system for training a trainable model to predict values of memory configuration parameters based on a value of a performance metric. The value of the performance metric is based on a threshold condition of a memory access operation performed on a memory device using a set of values of the memory configuration parameters. The output of the trainable model includes a set of predicted values of the memory configuration parameters. Responsive to determining that the set of predicted values of the memory configuration parameters satisfies a confidence criterion, the memory configuration parameters are updated to reflect the set of predicted values of the memory configuration parameters.

    Abstract: A programming failure is detected at a block of a memory device. Based on detecting the programming failure, the block is determined to be partially good based on a number of failed bytes in the block. An unfailing portion of the block is identified in response to determining the block is partially good. A record indicating the block is partially good and identifying the unfailing portion of the block is stored.

    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 wordline of a first die of the memory device. The processing device identifies, based on a first predefined value, a second wordline of a second die of the memory device, wherein the first predefined value is a shift in an index value of the first wordline of the first die of the memory device. The processing device further performs a second programming operation on a second set of cells associated with the second wordline of the second die, wherein the second wordline of the second die is associated with a different index value than the first wordline of the first die.
