Figure 7-21: Memory Bank Architecture 138
7.2.8 Memory Bank Simulation Figure 7-22 shows the erase and programming of two bits in the memory bank. The first bit gets erased and is not programmed while the second bit gets erased and is programmed. Figure 7-22 shows the floating gate voltage of the EEPROM cell that’s has been programmed and that been only erased. Figure 7-22: EEPROM Bank Simulation 139
