Abstract
A device for sensing a data in a multibit memory cell includes a reference voltage generating part for generating a plurality of reference voltages, a switching part for successively applying the plurality of reference voltages from the reference voltage generating part to a control gate on the multibit memory cell, a sensing part for comparing the data recorded in the multibit memory cell to the reference voltages when each of the plurality of reference voltages is applied thereto, a controlling part for generating a plurality of reference voltage selection signals to control the switching part, and applying a highest reference voltage to the clock signal controlling part so that the data is produced in response to a clock signal from the clock signal controlling part, and a clock signal controlling part for subjecting a signal from the sensing part and a highest reference voltage selecting signal to a logical operation in controlling an external main clock signal, and a latching part for latching the data from the controlling part.
