Abstract
A voltage detector including first and second current paths between a source voltage at a first level and current-limiting device joined to a second level of voltage, each path including an essentially-identical flash EEPROM memory device, one of the memory devices being programmed to have a lower threshold voltage than the other memory device; a circuit for providing a voltage to be measured to gate terminals of one of the memory devices and a percent of the voltage to be measured to the of one of the memory devices having the lower threshold voltage, and an output device connected to measure the current flowing through one of the current paths, the output device being arranged to conduct when current through the first path is greater than current through the second path and not to conduct when current through the first path is less than current through the second path.
