Abstract
Mapping information management for data storage devices is provided. A controller caches write data issued by a host in a temporary storage and then programs the cached write data from the temporary storage to a non-volatile memory. The controller uses a mapping information format to manage mapping information of logical addresses recognized by the host. As presented in the mapping information format, the values not greater than a first threshold value and mapped to the configuration information storage space of the non-volatile memory are at least partially used to point to the temporary storage, and the values greater than the first threshold value are mapped to the non-volatile memory.
