Abstract

An optimized non-volatile memory operating method. A data storage device has a plurality of non-volatile memory spaces, a plurality of command queues, and a controller. The command queues are provided to correspond to the non-volatile memory spaces one on one. The controller adds task switching commands into the command queues. The non-volatile memory spaces are operated through the same channel. The sharing of the same channel between the non-volatile memory spaces is optimized by the task switching commands.
