Abstract:
A memory cell includes a select device and a capacitor electrically coupled in series with the select device. The capacitor includes two conductive capacitor electrodes having ferroelectric material there-between. The capacitor has an intrinsic current leakage path from one of the capacitor electrodes to the other through the ferroelectric material. There is a parallel current leakage path from the one capacitor electrode to the other. The parallel current leakage path is circuit-parallel the intrinsic path and of lower total resistance than the intrinsic path. Other aspects are disclosed.
