摘要
Method and apparatus for managing data in a non-volatile memory (NVM) of a storage device, such as a solid-state drive (SSD). An initial temperature is stored associated with the programming of data to memory cells in the NVM. A current temperature associated with the NVM is subsequently measured. At such time that a difference interval between the initial and current temperatures exceeds a selected threshold, a preemptive parametric adjustment operation is applied to the NVM. The operation may include a read voltage calibration, a read voltage increment adjustment, and/or a forced garbage collection operation. The operation results in a new set of read voltage set points for the data suitable for the current temperature, and is carried out independently of any pending read commands associated with the data. The initial temperature can be measured during the programming of the data, or measured during the most recent read voltage calibration operation.
