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. The microprocessor executes the boot code loaded on the not-always-on area to load an in-system program from the non-volatile memory to the not-always-on area for execution of the in-system program. The script loaded on the always-on area is loaded from the non-volatile memory, and the non-volatile memory is searched to load the script to the always-on area in response to powering on a data storage device containing the non-volatile memory from a power-off state.
