Extended Hamming Code Algorithm and Its Application in FLASH/EEPROM Driver
Zhang Xue-lan · Ordnance Industry Automation · 2003
FLASH/EEPROM is a kind of read-only memory that is widely used in automobile and domestic appliance. But error may occur because of noise, shake, or magnetizing. The data stored should be encoded in order to provide the error checking and correcting function. Hamming code is a kind of error-correcting code. While the extended-Hamming code based on the Hamming code has 5 check bits by adding an additional 15th check bit. It can encode the 32-bit data, and also can decode the encoded data with the ability of 2-bit error checking and 1-bit error correcting. This algorithm can encode, check, and correct the data in FLASH/EEPROM successfully.
