Abstract: A data storage device waking up from a sleep mode rapidly is disclosed. The data storage device uses a controller to operate a non-volatile memory. The controller has a microprocessor and a volatile memory. The microprocessor loads boot code from the non-volatile memory to a not-always-on area of the volatile memory according to a script loaded on an always-on area of the volatile memory.
