ELECTRONIC DEVICE, MEMORY CELL, AND METHOD OF FLOWING ELECTRIC CURRENT

摘要

An electronic device includes two conductive electrodes. A first current path extends from one of the electrodes to the other and has a dominant thermally activated conduction activation energy of 0.5 eV to 3.0 eV. A second current path extends from the one electrode to the other and is circuit-parallel the first current path. The second current path exhibits a minimum 100-times increase in electrical conductivity for increasing temperature within a temperature range of no more than 50°C between 300°C and 800°C and exhibits a minimum 100-times decrease in electrical conductivity for decreasing temperature within the 50°C temperature range. Other embodiments are disclosed.
