Neuromorphic system exploiting the intrinsic characteristics of memory cells

摘要

The system has a set of neuron inputs (503, 504, 507, 508), a set of neuron outputs (505, 506), and a synaptic network (502) that is implemented by a memory cell e.g. conductive bridging RAM cell. The network is arranged for connecting the set of neuron inputs to outputs. A set characteristics of writing impulses (530-533) such as LTD impulses, and return impulses (514, 515) is deduced from intrinsic characteristics of the cell such that the combination of the impulses is levelled with the cell resulting in modification of resistance according to training rule selected beforehand. The rule is a spike timing depend plasticity type biological inspiration rule. Independent claims are also included for the following: (1) a method for determination of writing impulses and return impulses (2) a computer program comprising instructions for performing a method for determination of writing impulses and return impulses.
