    • A neuromorphic processing device (1) has a device input (2), for receiving an input data signal, and an assemblage of neuron circuits (3). Each neuron circuit (3) comprises a resistive memory cell (14) which is arranged to store a neuron state, indicated by cell resistance, and to receive neuron input signals (11) for programming cell resistance to vary the neuron state, and a neuron output circuit (15) for supplying a neuron output signals (12) in response to cell resistance traversing a threshold. The device (1) includes an input signal generator (4) connected to the device input (2) and the assemblage of neuron circuits (3), for generating neuron input signals (11) for the assemblage in dependence on the input data signal. The device (1) further includes a device output circuit (5), connected to neuron output circuits (15) of the assemblage, for producing a device output signal dependent on neuron output signals (12) of the assemblage, whereby the processing device (1) exploits stochasticity of resistive memory cells of the assemblage.
