Abstract
An example system can include a memory device and a processing device. The memory device can include a group of memory cells. The processing device can be coupled to the memory device. The processing device can be configured to determine a distance of a memory die from a center of a memory component. The processing device can be configured to perform a read disturb operation on the memory die based on the determined distance use a first voltage window for a set of memory cells of the group of memory cells during a first time period.
Claims20
An apparatus, comprising:
- a memory device including a group of memory cells;
- and
- a processing device coupled to the memory device and configured to:
- determine a distance of a memory die from a center of a memory component on which the memory die was manufactured;
- and
- perform a read disturb operation on the memory die based on the determined distance.
A method, comprising:
- determining a distance of a memory die from a center of a memory wafer on which the memory die was manufactured;
- determining a window size based on the determined distance;
- and
- performing a read disturb operation on the memory die within the window size.
A system, comprising:
- a memory device including a group of memory dies each comprising a group of memory cells;
- and
- a processing device coupled to the memory device and configured to:
- for each memory die of the group of memory dies, determine a respective distance from a center of a wafer on which the memory die was manufactured;
- determine a respective window size for each memory die of the group of memory dies based on the determined respective distances, wherein a greater distance from the center is associated with a smaller window size;
- and
- perform a read disturb operation on at least one memory die of the group of memory dies within the respective window size.
