Abstract
PURPOSE:To detect the state of potential stored in the charge storage section of memory cell, by detecting the potential change caused at the first node when a given amount of charge is taken off from the charge storage sections of the memory cell and dummy cell via the first node. CONSTITUTION:The voltage between the third nide 9 consisting of the gate of MOSTRQ7 for sense amplifier and the second node 3 consisting of the source is the threshold voltage to turn on MOSTRQ1 of the memory cell 1 selected from the state of interruption of TRQ7, and MOSTRQ7 is conudctive by causing small potential change to the second node 3 through the conduction of the charge storage section 10 and the second node 3, and until MOSTRQ7 is again cut off, the charge storage section 10 of the memory cell 1 and the charge storage section 11 of the dummy cell 4 take out a given amount of charge from the first node 8 consisting of the drain of MOSTRQ7. In this case, the potential change caused in the node 8 is detected, allowing to take greater potential amplitude of stored data and to increase the difference of detected voltages.
