Well you might have to allow for different drift rates. The activation energies may not be a fixed clean number.

This aside, isn't this just another application for a "storage class memory"?

Resistion:-Yes you are right, quantifying the differential drift rates for chalcogenides and as I suggested other materials with temperature and time will be necessary as a first order of business. The differential in drift rates that IBM were reporting for MLC-PCMs appeared to be consistent enough for that application. Before debating possible applications in the area of learning or storage it would be useful to run some Spice-like simulations to see what the minimum resistance level difference between the two hybrid resistors is necessary to allow the device to operate and the power ramp latency. In that respect I think for the IBM LIM a 20% difference in some circuit components was necessary for the memory to operate as both a LIM and SRAM. If there are any student readers or others who would like to volunteer for the single cell simulation task and demonstrate their expertise please step forward.
