Abstract:
The invention relates to an electronic memristive device that has a complementary analogue reconfigurable memristive bidirectional resistive switch. The device has a memristive layer sequence having a BFTO/BFO/BFTO three-ply layer and two electrodes. Titanium traps are arranged in the BFTO interfaces. As a result of mobile acid vacancies, the potential barriers at the interfaces of the electrodes with respect to the memristive layer sequence are in flexible form. By applying voltage pulses, the acid vacancies can be shifted from the interface with respect to the first electrode to the interface with respect to the second electrode, with raising of the potential barrier at one electrode bringing about complementary lowering of the potential barrier of the other electrode. The method according to the invention for operating the device proposes adapted writing processes that use the overlaying of writing pulse sequences to achieve stipulation of a state pair of complementary resistor states. In conjunction with reading pulses of adapted polarity, the device can implement fuzzy logic and be operated as an artificial synapse with the realisation of all four learning curves for complementary learning. A plurality of options for the use of the device operated according to the invention are proposed

Claim (Index 3):
Method according to  claim 1 , wherein, prior to the writing process, as defined in claim  1 a), at least one initialisation pulse, the absolute value of which reaches or exceeds the absolute value of the minimum writing voltage for the minimum writing period that is dependent on the minimum writing voltage, is applied to the first or second electrode of the memristive device, wherein\n an initialisation pulse having a positive voltage bring S  the memristive device into a low resistance state (LRS) in a first current direction, and writes the state pair (PLRS, NHRS), or an initialisation pulse having a negative voltage bring S  the memristive device into a high resistance state (HRS) in a first current direction, and writes the state pair (PHRS, NLRS), and wherein the written state pairs (PLRS, NHRS) or (PHRS, NLRS) each correspond to complementary end states and the initialisation pulse having a positive voltage precedes a writing pulse sequence pair having a negative temporal offset, or the initialisation pulse having a negative voltage precedes a writing pulse sequence pair having a positive temporal offset.
