Abstract
The present disclosure provides a storage cell or storage structure having a static RAM-like operational behavior while nevertheless providing non-volatile storage capability on a single bit basis. To this end, a non-volatile storage element, such as a ferroelectric transistor element, may be provided within an inverter structure so as to allow the storage of a logic state at any desired operational phase by increasing the voltage difference used for operating the inverter structure. In illustrative embodiments, the stored logic state may be re-established during a power-up event.
