I've been curious about memristors for a while, and decided to see if I could
model one in LTspice (since I didn't find one there). This is the result.
This is not by any means definitive, just an example of the memristor as
described in one of the more well-known papers on the subject.

This was tested successfully with LTspice IV 4.17u
    http://www.linear.com/designtools/software/#LTspice

I installed this as follows, where %LTINSTALL% = the install path
    (e.g. "C:\Program Files\LTS\LTspiceIV")

    Memristor_sim.asc -> %LTINSTALL%\
    Memristor_sim.plt -> %LTINSTALL%\
    memristor.asy     -> %LTINSTALL%\lib\sym\
    memristor.sub     -> %LTINSTALL%\lib\sub\

Simulation:
    Open Memristor_sim.asc
    Select "Simulate" -> "Run"
    Click on the graph tab
    Select "Plot Settings" -> "Open Plot Settings File"
    Select Memristor_sim.plt
    This output should match what you see in the Memristor_sim_example.png file
