A resistor would give you a straight line where the slope is its resistance. Voltage goes up or down it traces out the same line of current at any instant voltage.
This dude gives a different current based on previous voltage, it remembers its past state, basically.
It has to pass thru zero otherwise we call it a "rechargeable battery". A nicad would have an offset of 1.2 volts at zero current, not passing thru zero (unless it was totally dead and leaking) Also battery frequency response is pretty dismal, being chemical electroplating devices.
If you look at a magnetic hysteresis loop there is some family resemblance. Sticking a cap or inductor on a curve tracer looks quite a bit different and often will not pass thru origin point either (unless you run the device at resonant freq which is whole nother kettle of worms)
Its also kinda frequency dependent and the limiting stage of a memresistor at super high frequencies would be a boring resistor and the way the gap shrinks with freq is important to prove its a "real" memresistor. What's interesting about "recent" news is that its possible to make some pretty fast ones now a days in a research lab and some prototypes are supposedly shipping etc. I would have to think for a second, what is the limiting behavior of a 2 pin semiconductor device... if a memresistor is a resistor I think a diode would at high freq be basically a capacitor, at least when reverse biased (the famous varactor diode). There is a weak varactor effect of forward biased diodes too BTW, although its not terribly useful.
