Abstract
A data storage device includes a memory device and a controller coupled to the memory device. When a boot operation of the data storage device is initiated, the controller retrieves a relevant boot file from the memory device to boot the data storage device with. The relevant boot file to be retrieved from a plurality of boot files may be determined by a write temperature corresponding to the temperature of when the boot file was programmed to the memory device and a read temperature of the boot file during the boot operation. Each boot file of the plurality of boot files is programmed using different programming parameters in order to cover a range of possible retention levels.
