Changes - Switch Model in PSpice is VSWITCH, it is not SW.
Second problem is with F device "Fmem" - here you can use a E device as controlling source. The change above is convert E device to V - however you need to make sure model intent is not altered. Change above does not gurantee that
 

Thank you very much for your reply. I need one more and last help. I am also getting error in the following code aswell. Please can you help me out with this.

.SUBCKT memristor plus minus PARAMS:

Gx 0 x value={I(Emem)*uv*Ron/D^2*f(V(x),p)}
Cx x 0 1 IC={(Roff-Rinit)/(Roff-Ron)}
Raux x 0 1T
Emem plus aux value={-I(Emem)*V(x)*(Roff-Ron)}
Roff aux minus {Roff}

Echarge charge 0 value={SDT(I(Emem))}
