UPDATING READ VOLTAGES

摘要

A data storage device includes a controller that is configured to determine a first read voltage for a first page of a non-volatile memory (e.g., a lower page of a Multi-Level Cell flash memory device). The controller is also configured to determine a second read voltage for a second page (e.g., an upper page) of the non-volatile memory by applying an offset value to the first read voltage. The controller is also configured to store data identifying the first read voltage and the second read voltage.
