Abstract
A processing device performs a multi-pass programming operation on the memory device resulting in first pass programming distributions and second pass programming distributions. One or more read level thresholds between the second pass programming distributions are changed. Responsive to changing the one or more read level thresholds between the second pass programming distributions, one or more read level thresholds between the first pass programming distributions are adjusted based on the changes to the one or more read level thresholds between the second pass programming distributions.
Claims20
A system comprising:
- a memory device;
- and
- a processing device, operatively coupled to the memory device, to perform operations comprising:
- performing a multi-pass programming operation on the memory device resulting in first pass programming distributions and second pass programming distributions;
- changing one or more read level thresholds between the second pass programming distributions;
- and
- responsive to changing the one or more read level thresholds between the second pass programming distributions, adjusting one or more read level thresholds between the first pass programming distributions based on the changes to the one or more read level thresholds between the second pass programming distributions.
A method, comprising:
- performing a multi-pass programming operation on a memory device resulting in first pass programming distributions and second pass programming distributions;
- changing one or more read level thresholds between the second pass programming distributions;
- and
- responsive to changing the one or more read level thresholds between the second pass programming distributions, adjusting one or more read level thresholds between the first pass programming distributions based on the changes to the one or more read level thresholds between the second pass programming distributions.
A non-transitory computer-readable medium comprising instructions that, responsive to execution by a processing device, cause the processing device to perform operations comprising:
- performing a multi-pass programming operation on a memory device resulting in first pass programming distributions and second pass programming distributions;
- changing one or more read level thresholds between the second pass programming distributions;
- and
- responsive to changing the one or more read level thresholds between the second pass programming distributions, adjusting one or more read level thresholds between the first pass programming distributions based on the changes to the one or more read level thresholds between the second pass programming distributions.
