  • Tracking of optimum read voltage thresholds in nand flash devices
    Patent number: 10210926
    Abstract: A method for biasing read voltage for flash memory in a storage system, performed by the storage system, is provided. The method includes tracking bit flips in a first direction and bit flips in a second direction in data reads of the flash memory in the storage system, based on error correction of the data reads. The method includes comparing or forming a ratio of the bit flips in the first direction to the bit flips in the second direction or the bit flips in one of the first direction or the second direction to a total number of bit flips. The method includes adjusting read voltage level for the flash memory in the storage system, based on the comparing or the forming the ratio.
