METHOD AND MEANS FOR OPERATING A COMPLEMENTARY ANALOGUE RECONFIGURABLE MEMRISTIVE RESISTOR INTERRUPTER AND USE THEREOF AS AN ARTIFICIAL SYNAPSE

摘要

The invention relates to an electronic memristive component that has a complementary analogue reconfigurable memristive bidirectional resistor interrupter. The component has a memristive layer sequence having a BFTO/BFO/BFTO three-ply layer and two electrodes. Titanium traps are arranged in the BFTO boundary layers. As a result of mobile acid vacancies, the potential barriers at the boundary layers of the electrodes with respect to the memristive layer sequence are in flexible form. By applying voltage pulses, the acid vacancies can be displaced from the boundary layer with respect to the first electrode to the boundary layer 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 component proposes adapted write processes that use the overlaying of write pulse sequences to achieve stipulation of a state pair of complementary resistor states. In conjunction with read pulses of adapted polarity, the component 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 component operated according to the invention are proposed.
