Abstract:
Methods and systems for improving the reliability of stored data in the presence of cross-temperature variation are described. To reduce the number of data errors caused by cross-temperature variation, two or more sensing passes may be performed corresponding with two or more different sensing times. The amount of shifting in the memory cell threshold voltages may be determined on a per-bit basis or on a cell-by-cell basis based on the sensing operations performed during the two or more sensing passes. The stored data states may be assigned based on the amount of shifting in the memory cell threshold voltages during the two or more sensing passes and the type of cross-temperature variation present (e.g., whether the memory cells were programmed at a temperature above 65 degrees Celsius and read back at a temperature below 25 degrees Celsius).

Claim (Index 17):
An apparatus, comprising:\n a set of memory cells; a temperature sensor configured to determine a temperature associated with the set of memory cells; a sensing circuit configured to determine a first set of threshold voltage zone data for the set of memory cells based on a first sensing time and determine a second set of threshold voltage zone data for the set of memory cells based on a second sensing time different from the first sensing time, the sensing circuit configured to generate a first set of data using the first set of threshold voltage zone data and the second set of threshold voltage zone data assuming a first type of cross-temperature variation and generate a second set of data using the first set of threshold voltage zone data and the second set of threshold voltage zone data assuming a second type of cross-temperature variation different from the first type of cross-temperature variation; and an error detection circuit configured to acquire the first set of data and the second set of data, the error detection circuit configured to detect that the second set of data has less than a threshold number of bit errors and output the second set of data in response to detection that that the second set of data has less than the threshold number of bit errors.
