Write the latest data to the next available location along with its 'EEPROM address'. When you run out of room on the first page, write all of the latest values to the second page and erase the first. Begin writing values where you left off on page 2. Webbytes or words—called a block, sector, or page—are electrically erased at the same time. Due to the erase operation being much faster than the prior EPROM or EEPROM devices, these devices came to be called flash erase EEPROM, or simply flash memories.
