Abstract
Aspects of the disclosure provide systems and methods for adaptive data retention management in non-volatile memory. A solid state device (SSD) includes non-volatile memory (NVM) for storing data. The SSD is configured to determine a temperature of the NVM. If the temperature of the NVM is below a predetermined temperature, the SSD maintains a data retention refresh rate of the data stored in the NVM. If the temperature of the NVM is equal to or above the predetermined temperature, the SSD adjusts the data retention refresh rate at a first rate and then a second rate, each adjustment based on the temperature of the NVM. The first rate and the second rate are different, for example, the second rate is less than the first rate.
