Abstract
An embodiment is a technique to classify a flash device. Test data to a flash device are accessed in unscramble and scramble modes under a test mode. Error correcting code (ECC) results are recorded on the test data for the unscramble and scramble modes. A device quality figure is calculated based on the ECC results for the unscramble and scramble modes. The flash device is classified using the device quality figure.
