  • Publication number: 20160086675
    Abstract: Methods for reducing cross-temperature dependent word line failures using a temperature dependent sensing scheme during a sensing operation are described. In some embodiments, during a read operation, the sensing conditions applied to memory cells within a memory array (e.g., the sensing time, source line voltage, or bit line voltage) may be set based on a temperature of the memory cells during sensing and a word line location of the memory cells to be sensed. In one example, the memory array may comprise a NAND memory array that includes a NAND string and the sensing time for sensing a memory cell of the NAND string and the source line voltage applied to a source line connected to a source end of the NAND string may be set based on the temperature of the memory cells during sensing and the word line location of the memory cells to be sensed.
