Techniques for reducing read voltage threshold calibration in non-volatile memory

A non-volatile memory includes a plurality of cells each individually capable of storing multiple bits of data including bits of multiple physical pages including at least a first page and a second page. A controller of the non-volatile memory determines a first calibration interval for a first read...

Zusammenfassung:A non-volatile memory includes a plurality of cells each individually capable of storing multiple bits of data including bits of multiple physical pages including at least a first page and a second page. A controller of the non-volatile memory determines a first calibration interval for a first read voltage threshold defining a bit value in the first page and a different second calibration interval for a second read voltage threshold defining a bit value in the second page. The second calibration interval has a shorter duration than the first calibration interval. The controller calibrates the first and second read voltage thresholds for the plurality of memory cells in the non-volatile memory based on the determined first and second calibration intervals.
