Abstract: One or more embodiments disclosed herein describe a nonvolatile, analog programmable resistive memory with a plurality of memory states. The programmable resistive memory includes a substrate, an IGZO resistive layer and electrical contacts. The electrical contacts are deposited on the IGZO layer, in the same plane. The electrical contacts may have various shapes in order to obtain spatially variable distances between the electrical contacts. The resistance of the resistive memory can be brought from an initial low value to a plurality of various higher values by applying electrical voltage pulses with various durations and various amplitudes and/or by applying one or more DC voltage sweeps. Also, the high voltage limit during the DC voltage sweeps could be set at values ranging from few volts to few tens of volts. In this manner, the IGZO programmable resistive memory could be set in a plurality of memory states.

Abstract: A system and method for generating encryption keys on multiple devices, without transferring the keys. At least one sender memristor is set using at least one sender setting value. At least one sender reading value is applied to the at least one sender memristor to generate at least one sender output value. A string of characters is determined from the at least one output value based on a sender table. Data is encrypted with the string of characters. The encrypted data is transmitted to a receiver through a first channel. The at least one sender setting value or the at least one sender reading value or both is transmitted to the receiver through a second channel different from the first channel. The at least one sender setting value or the at least one sender reading value or both is applied to at least one receiver memristor to generate at least one receiver output value. A receiver table is used to determine the string of characters from the at least one receiver output value.

Abstract: A system and method used for generating encryption keys on multiple devices and for encrypted data transfer between two or multiple devices. A sender system includes at least one sender device with nonlinear I-V characteristics. A receiver system includes at least one receiver device with nonlinear I-V characteristics. The at least one sender device with nonlinear I-V characteristics generates at least one sender output value used to create a string of characters or bits or bytes or numbers. The string of characters is used to encrypt data which is sent to the receiver device. The at least one receiver device with nonlinear I-V characteristics generates at least one receiver output value, and uses the at least one receiver output value to create the string of characters from the at least one receiver output value. A receiver processing unit generates the data from the encrypted data using the string of characters.
