摘要:
A MFMOS one transistor memory structure for ferroelectric non-volatile memory devices includes a high dielectric constant material such as ZrO2, HfO2, Y2O3, or La2O3, or the like, or mixtures thereof, to reduce the operation voltage and to increase the memory window and reliability of the device.
