Title: Data read-out method and semiconductor memory
Inventor: TAMURA TETSURO
IPC: G11C11/22
Filed: 2000-04-11
Abstract: PROBLEM TO BE SOLVED: To secure output margin required for read-out and to prolong a service life of a device even when imprint occurs and quantity of polarization is varied in a ferroelectric memory using a ferroelectric film. SOLUTION: This data read-out method is such a method that data stored in ferroelectric capacitors C0, C1 in which a plate line PL is connected to one side of electrodes and a bit line BL is connected to the other side of electrodes are amplified and read out by performing sense operation after a pulse 10 is inputted to a plate line. A signal (ΔP10) from the bit line BL is outputted based on the pulse 10, and the sense operation is performed after output of the signal is reduced from the peak value. Output of the signal can be reduced by securing a time from inputting of the pulse 10 to starting of sense operation by the prescribed time, and output margin of the signal can be secured by output reduction of the bit line BL caused by imprint effect of the capacitor.
