Retention characteristic and extracted activation energy. (a) The retention characteristic at 25°C of Gd2O3-NC memories with nanostructure tunneling layer. (b) The extracted activation energy of two charge loss mechanisms. The retention characteristic can be divided into two parts which have different charge loss rates.
