A reference current integrator and a sensed current integrator are coupled to form a differential sense amplifier. The differential sense amplifier is coupled to receive a bitline current signal from a flash memory, and the reference current integrator is coupled to receive a current signal from a reference memory cell. Integration continues until a desired voltage or time is reached, resulting in a sufficiently reliable output. The differential current integrating sense amplifier is also used for instrumentation, communication, data storage, sensing, biomedical device, and analog to digital conversion.
