The device consists of a thin titanium dioxide film 50nm in between two electrodes 5nm one Titanium and the other latinum. Initially, there are two layers to the titanium dioxide film, one of which has a slight depletion of oxygen atoms. The oxygen vacancies act as charge carriers and this implies that the depleted layer has a much lower resistance than the no depleted layer.

The device consists of a thin titanium dioxide film 50nm in between two electrodes 5nm one Titanium and the other latinum. Initially, there are two layers to the titanium dioxide film, one of which has a slight depletion of oxygen atoms.

The oxygen vacancies act as charge carriers and this implies that the depleted layer has a much lower resistance than the no depleted layer. When an electric field is applied, the oxygen vacancies drift, changing the boundary between the high-resistance and low-resistance layers.

Thus the resistance of the film as a whole is dependent on how much charge has been passed through it in a particular direction, which is reversible by Changing the direction of current.

Chua defined the element as a resistor whose resistance level was based on the amount of charge that had passed through the memristor Memristance Memristance is a property of an electronic component to retain its resistance level even after power had been shut down or lets it remember or recall the last resistance it had before being shut off.

Theory Each memristor is characterized by its memristance function describing the charge-dependent rate of change of flux with charge.

Of course, nonzero current implies instantaneously varying charge. Alternating current, however, may reveal the linear dependence in circuit operation by inducing a measurable voltage without net charge movement as long as the maximum change in q does not cause much change in M. Voltage characteristics This new circuit element shares many of the properties of resistors and shares the same unit of measurement ohms.

However, in contrast to ordinary resistors, in which the resistance is permanently fixed, memristance may be programmed or switched to different resistance states based on the history of the voltage applied to the memristance material.

This phenomena can be understood graphically in terms of the relationship between the current flowing through a memristor and the voltage applied across the memristor. In ordinary resistors there is a linear relationship between current and voltage so that a graph comparing current and voltage results in a straight line.

However, for memristors a similar graph is a little more complicated as shown in Fig. In contrast to the straight line expected from most resistors the behavior of a memristor appear closer to that found in hysteresis curves associated with magnetic materials.

It is notable from Fig. These two straight line curves may be interpreted as two distinct resistance states with the remainder of the curve as transition regions between these two states. Voltage curve demonstrating hysteretic effects of memristance. Idealized hysteresis model of resistance vs.

For a voltage above threshold VL1 the resistance switches from a high to a low level and for a voltage of opposite polarity above threshold VL2 the resistance switches back to a high resistance. Initially, there are two layers to the film, one of which has a slight depletion of oxygen atoms. The oxygen vacancies act as charge carriers, meaning that the depleted layer has a much lower resistance than the non-depleted layer.

When an electric field is applied, the oxygen vacancies drift changing the boundary between the high-resistance and low-resistance layers.

Since the memristor displays fast ion conduction at nanoscale, it is considered a nanoionic device. They can also be fashioned into non-volatile solid-state memory, which would allow greater data density than hard drives with access times potentially similar to DRAM, replacing both components.

HP prototyped a crossbar latch memory using the devices that can fit gigabits in a square centimeter.
