ABSTRACT:
A multilevel sensing circuit and sensing method therefor. The multilevel sensing circuit has first and second sense amplifiers connected to each bit line to which left and right memory cells of a DRAM are connected, a feedback element connected to each bit line, and an isolating transistor including an NMOS transistor connected between the comparator and a sensing input node of the second sense amplifier. The isolating transistor is turned on after a second sensing operation is sufficiently carried out and turned off before a restore operation is carried out.
