Abstract
The present invention relates to a memory structure and, more particularly, to a programmable memory structure erasable by electricity and a method for protecting the same. The present invention partitions a memory into a main memory section and a special memory section. A logical controller and an error detector are installed in the special memory section. When the system is booted, the special memory section will drive the error detector to detect whether the data in the main memory section is damaged. If data is lost, a backup data is read from a hard disk device via the logical controller to successfully complete booting procedures. On the other hand, this backup data will be directly duplicated into the main memory section to restore the damaged data. Thereby the data therein can be prevented from losing.
