Boosting voltage circuit for use in flash memory device, has level detector receiving programming input signals, detecting active input signals and delivering detected signals of varying weight that depends upon active signals

摘要

The circuit has a level detector (331) receiving a set of programming input signals and detecting which of the signals are active. The detector outputs detected signals of varying weight based upon the active signals. A signal generator (333) receives the detected signals from the detector and outputs a generated signal with a varying voltage level proportional to the varying weight of the detected signals. An independent claim is also included for a method of controlling a bias source in a memory device, comprising a set of programming input signals.
