As Alan mentioned, if you read it with an AC current then you will have put a net zero current flow through it. (You slightly increase the resistance, then slightly decrease it, setting it back where it was.)

Also it is likely that the device may require significantly more current flow to set the value than it does to read the value.

I am sure, however, that the uses of this device will expand beyond merely memory in ways that we cannot, at present, imagine.
