In this work, the utility of PCMO RRAMs as an enabler for large scale stochastic recurrent neural networks like Boltzmann machines is proposed. The parameters affecting the set-time stochasticity are identified. With HRS andVSetfixed,tSetdistribution is fully determined across cycles and time. The asymmetric nature of stochasticity between set and reset is highlighted. Deterministic and gradual state control in the Reset operation allows HRS controllability to enable drift-free set stochasticity over many iterations. The reduced drift enables the solution of problems greater than 1000 nodes for the max-cut graphical optimization using Boltzmann machines which is 20×higher than electrical-input only method of stochasticity generation. Further, HRS controllability allows tuning out of the device-to-device variability effects improving solution quality by 10×compared to a system with realistic variations. The properties of PCMO RRAM neuron as a stochastic neuron with a controllable internal state makes it the choice of device for implementing stochasticity and weights in large scale Boltzmann machines.
Yes Guv, but this is science and in science first we demonstrate and then we do...
I wondered why they left it till last run to change the formula... Control, the final piece of the puzzle for Reram tech both for endurance & retention.. The only real challenge left... And yes it does mean they can play in the neural space if they want but the main game is still SCM I believe..4. Conclusion
And for that (SCM Desireables) we have the doc link below: Complete with link to Excel file tables on all key metrics and questions..
So pls feel free to go and have a rummage around.
Still a bit unknown about Mott Trans but that won't be for long... Best projected was 5-10nm but I feel they may have gone a little better with effort at IMEC considering the report has it demonstrated at 110nm & we know 4DS went to 40nm..
Key though is the 2ns W/E time with Cycles projected at 10^15, although anything over 10^9 is suitable for M-SCM as it stands now.
And of course it stacks vertically in an array.. One of few that do ;-) 8tey
