Array source line (AVSS) controlled high voltage regulation for programming flash or EE array

A method for programming a Flash memory array comprises coupling at least one of a current source and a potential source to at least one selected bitline of a Flash memory array, monitoring a potential VAVSS of an array VSS line by means of a comparator, allowing the array VSS line to electrically f...

Zusammenfassung:A method for programming a Flash memory array comprises coupling at least one of a current source and a potential source to at least one selected bitline of a Flash memory array, monitoring a potential VAVSS of an array VSS line by means of a comparator, allowing the array VSS line to electrically float until the potential VAVSS is approximately equal to a reference potential Vref, and terminating the programming by de-coupling at least one of the current source and the potential source.
