CELL DATA SENSING CIRCUIT OF SEMICONDUCTOR MEMORY DEVICE

摘要

PURPOSE: A cell data sensing circuit of semiconductor memory device is provided to stably make operation of circuit and improve confidence of a semiconductor memory device. CONSTITUTION: The circuit comprises a memory cell data detector for detect a sensing signal according to a data stored in a memory cell, a reference signal generator for generating two reference signal stored in two or more reference cells connected in serial, and a comparator for receiving the sensing signal from the memory cell data detector and the reference signal from the reference signal generator and comparing the sensing signal with the reference signal. The data stored in the memory cell is detected by the signal outputted from the comparator.
