Abstract
An electrically erasable programmable read-only memory (EEPROM) with a ripple programming mode. Memory cells in an the EEPROM array include floating-gate transistors with control gates coupled to corresponding word lines, and drain electrodes coupled to corresponding bit lines. A memory cell is programmed by applying a high programming voltage to its control gate along with applying a high programming voltage to its drain. Multiple memory cells within a row can be programmed by applying the programming voltage to the word line of that row, during which multiple bit lines receive their programming voltage, without removing the word line programming voltage when changing the programming from one bit line to another.
