Abstract
A non-volatile storage apparatus stores data in the non-volatile memory cells by programming the non-volatile memory cells to a set of data states and reads data stored in the non-volatile memory cells by sensing for a set of read reference levels for the data states. To address data retention issues, including memory cells having the threshold voltages drift over time, one or more of the set of read reference levels are shifted based on sensing the non-volatile memory cells for two different conditions during a single ramping up of a voltage signal applied to the non-volatile memory cells.
