HARD DISK DRIVE CACHE MEMORY AND PLAYBACK DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an improved device for saving battery power.

SOLUTION: In a computer system, a NOR emulating device using a controller and a NAND memory can be used instead of a main memory or of a BIOS NOR memory. The emulating device can therefore function as a boot possible memory. Additionally, the device can function as a cache for a hard disk drive. By adding a MP3 player controller to the device, the device also functions as a stand-alone audio playback device during a time when a PC is power-off or at rest.
