    Abstract: A preheating procedure for a non-volatile memory that can be used in a wide range of ambient temperatures is shown. The controller of the non-volatile memory operates the non-volatile memory to preheat the non-volatile to a temperature target. The controller avoids writing valid data to the non-volatile memory until preheating the non-volatile memory to the temperature target. The controller may write or read dummy data to or from the non-volatile memory until preheating the non-volatile memory to the temperature target.

    Abstract: A hybrid data storage device is shown. In addition to a non-volatile memory, the hybrid data storage device has a volatile memory. A microcontroller of the data storage device generates and maintains a first mapping table and a second mapping table. According to the first mapping table, specific logical addresses are mapped to the volatile memory. The second mapping table records mapping information between logical addresses, including the specific logical addresses, and the non-volatile memory. When the data storage device is powered on, the microcontroller uploads data read from the non-volatile memory to the volatile memory according to the first mapping table and the second mapping table.
