Abstract
A system comprises a memory device comprising a plurality of memory cells; and a processing device coupled to the memory device, the processing device configured to manage optimization target data that at least initially includes read levels in addition to a target trip, wherein the optimization data is managed based on iteratively calibrating the read levels and removing the calibrated levels from the optimization target data.
Claims20
An apparatus, comprising:
- a plurality of memory cells configured to store data;
- and
- a processing device coupled to the plurality of memory cells, the processing device configured to manage optimization target data that at least initially includes read levels in addition to a target trim, wherein
- the target trim corresponds to an adjustment level used to adjust voltage for reading a portion of the plurality of memory cells;
- and
- the optimization target data is managed based on
- iteratively calibrating the read levels based on associated results of reading the stored data;
- and
- removing one or more calibrated read levels from the optimization target data when the one or more calibrated read levels satisfy a target condition.

A method for operating an apparatus that includes a plurality of memory cells configured to store data, the method comprising:
- iteratively calibrating read levels used to read the stored data based on corresponding read results, wherein
- the read levels are tracked via optimization target data that at least initially includes at least one read level in addition to a target trim, and
- the target trim corresponds to an adjustment level used to adjust voltage for reading a portion of the plurality of memory cells;
- and
- removing one or more calibrated read levels from the optimization target data when the calibrated read level satisfies a calibration condition.
