Abstract
A sensing circuit for multi-level flash memory is disclosed. The advantages of the sensing circuit are reducing the circuit size, reducing the testing time for tuning reference voltage and maintaining a constant difference between two approximate reference voltages. The sensing circuit comprises a reference voltage generator which includes a number of serial connected resistive devices and provides several reference voltages by voltage division; a data saving circuit outputs a data voltage; a comparing circuit compares the data voltage with the several reference voltages to output a comparing signal; a decoder receives and then decodes the comparing signal to output the data.
