SYSTEM DEVICE BOOTED BY USING FLASH MEMORY AND SYSTEM BOOTING METHOD THEREOF

摘要

PURPOSE: A system device booted by using a flash memory and a system booting method thereof are provided to boot the system device without a separate hardware controller or an additional memory, and boot the system device through a software scheme by using a power-on auto-read function. CONSTITUTION: The system device comprises a CPU(210), a sequential access flash memory(212), and a system(214). The data is transmitted among the CPU and the sequential access flash memory, and the system memory by using a system bus(216). The sequential access flash memory includes a boot handler code and a bootstrap loader code in the first page, and stores the bootstrap code, an OS(Operating System) code, and application programs and user data. The boot handler code duplicates the bootstrap loader code to a region of the system memory. The bootstrap loader code loads the bootstrap code and the OS code to the system memory.
