Abstract
A reprogramming device of a flash memory includes: a flash memory which stores BIOS data for a computer system; a central process unit which outputs an address signal after reading the BIOS data from the flash memory; random access memory which stores new BIOS data; and a controller driven by the address signal of the central process unit, which writes the new BIOS data of the random access memory on the flash memory. The device also includes a switch which controls an operation of the flash memory; and a reprogrammer which makes it possible to reprogram the flash memory. The reprogramming can occur even when the flash memory is mounted in a main board and when the flash memory can not boot the computer system because of damaged BIOS data.
