    摘要: A reprogrammable integrated circuit (IC) including overwritable nonvolatile storage cells. Cell contents are compared in a differential sense amplifier against a variable reference signal that has a number of selectable reference levels corresponding to reprogrammed cell threshold voltages. With each write cycle the nonvolatile storage cells are overwritten and then, compared against a different, e.g., higher, selectable reference level.
