wish some collaboration with these kind of chip

Neuroinformatics researchers from the University of Zurich and ETH Zurich together with colleagues from the EU and U.S. have demonstrated how complex cognitive abilities can be incorporated into electronic systems made with “neuromorphic” chips.

neuromorphic computing is analog.
analog is OVER.

nah, neuromorphic is combination of analog & digital.
if analog is dead, then digital dead too, see qubit.

multi-neuron chip comprising an array of analog/digital silicon neurons and synapse circuits

That's really an interesting project. There's actually many benefits to analog processing that would especially benefit neural and signal processing. Namely precision. In digital processing we've generally got floats and/or large bit ranges. Analogue values are near infinitely precise, shape-sensitive and time-sensitive by nature. The precision, especially in the upper and lower boundaries of your total-lifetime-input for a neural map is pretty significant to it's ability to achieve context.

It's thought by many circles that more and more hybrid digital/analogue/highly parallel systems will be on the rise on the road to quantum computing. I certainly support that viewpoint as it seems the most logic road forward we have. A lot of the holographic display technologies require analog measurement and output as well =)

looks like ibm chip made some progress.

Six years ago, IBM and our university partners embarked on a quest—to build a brain-inspired machine—that at the time appeared impossible. Today, in an article published in Science, we deliver on the DARPA SyNAPSE metric of a one million neuron brain-inspired processor. The chip consumes merely 70 milliwatts, and is capable of 46 billion synaptic operations per second, per watt–literally a synaptic supercomputer in your palm.

If you ever had bad experiences because of noise, drift, delay and echo, you'd think otherwise. ;-)

On the other hand, the brain itself is built on top of a completely unreliable, analog foundation. If our computers would be as reliable as biological neurons, nobody would want to use them. What we have, though, is a massive amount of them - which makes all the many failures all the time tolerable most of the time.
