Abstract
Devices and techniques for NAND cell encoding to improve data integrity are disclosed herein. A high-temperature indicator is obtained and a write operation is received. The write operation is then performed on a NAND cell using a modified encoding in response to the high-temperature indicator. The modified encoding includes a reduced number of voltage distribution positions from an unmodified encoding without changing voltage distribution widths, where each voltage distribution corresponds to a discrete set of states an encoding.
