Abstract

A flash memory that shares a booting function and a booting program, and an apparatus and method for protecting the same in an AT Attachment Packet Interface (ATAPI) drive. The flash memory includes a first boot zone, where a booting program is stored, a second boot zone, where a backup of the booting program is stored, and a data zone, where an executable and downloaded firmware program is stored, wherein the corresponding booting program in either of the first or second boot zones which has no error is executed when an error is detected in the alternate first or second boot zone. Accordingly, it is possible to restore a flash memory damaged due to some external cause to its original state, thereby reducing costs for replacement of the damaged flash memory.

Description

[0001] related application [0002] This application claims the priority of Korean Patent Application No. P2002-76037, the filing date of which is December 2, 2002, the disclosure of which is hereby incorporated by reference. technical field [0003] The present invention relates to a flash memory including a boot program, a copy of the boot program, and a firmware program, as well as a device and a method for protecting the flash memory. Background technique [0004] The flash memory of the AT Attachment Packet Interface (ATAPI) driver stores a firmware program, which is sent from the host. The firmware program previously stored in the flash memory can be updated with a new version of the firmware program. However, the boot area of ​​the flash memory, in which the boot program is stored, may be damaged due to some external factors. In this case, it is impossible to restore the damaged boot sector to its original state, so that the flash memory becomes unusable. Contents...
