Abstract
Methods and systems are disclosed for adjusting read/verify bias conditions for non-volatile memory (NVM) cells to improve performance and product lifetime of NVM systems. System embodiments include integrated NVM systems having a NVM controller, a bias voltage generator, and an NVM cell array. Further, the NVM systems can store performance degradation information and read/verify bias condition information within storage circuitry. The disclosed embodiments adjust read/verify bias conditions for the NVM cells based upon performance degradation determinations, for example, temperature-based performance degradation determinations.
