摘要:
A MFMOS one transistor memory structure for ferroelectric non-volatile memory devices includes a high dielectric constant material such as ZrO 2 , HfO 2 , Y 2 O 3 , or La 2 O 3 , or the like, or mixtures thereof, to reduce the operation voltage and to increase the memory window and reliability of the device.
