PULSE RESPONSE FOR HIGH-SPEED NONDESTRUCTIVE READOUT IN FERROELECTRICS

Pulse responses for high-speed nondestructive readout in ferroelectric s have been studied using a ferroelectric lead zirconate titanate thin film as a memory capacitor. A critical pulse width t(), defined as t he maximum of the pulse width for which the system returns to the init ial polarization state after the removal of the applied pulse field. i s found to exist, suggesting the possibility of a nondestructive reado ut in ferroelectric memory. The observed pulse responses are compared with those of circuit simulation.
