发明名称 A VOLTAGE BOOST CIRCUIT USING SUPPLY VOLTAGE DETECTION TO COMPENSATE FOR SUPPLY VOLTAGE VARIATIONS IN READ MODE VOLTAGES
摘要 Flash memory array systems and methods are disclosed for producing a supply regulated boost voltage, wherein the application of a supply voltage to a supply voltage level detection circuit (e.g., analog to digital converter, digital thermometer) which is used to generating one or more supply voltage level detection signals from measurement of the supply voltage level applied to the voltage boost circuit, which may be used as a boosted wordline voltage for the read mode operations of programmed memory cells, and wherein the supply voltage level detection signals are applied to a boosted voltage compensation circuit to generate one or more boosted voltage compensation signals which are applied to a voltage boost circuit operable to generate a regulated boosted voltage for a flash memory array of programmed core cells. Thus, a fast compensation means is disclosed for the VCC power supply variations typically reflected in the output of the boost voltage circuit supplied to the word line of the flash memory array, thereby generating wordline voltages during the read mode which are substantially independent of variations in the supply voltage.
