1. A neuromorphic data processing device, comprising: a plurality of spiking neurons, each said spiking neuron including: an integrator configured to: receive successive analog pulses, each having a certain value, and accumulate the certain values of the received analog pulses in a recorded value, referred to as an accumulation value; a discharger configured to: emit a pulse, referred to as a discharge pulse, according to the accumulation value; and a silicon support having two surfaces, wherein a portion of each of the spiking neurons is provided on at least one of the two surfaces, wherein the integrator of each said spiking neuron has a metal Through-Silicon Via (TSV) between the two surfaces of the silicon support, the metal TSV forming a capacitor with the silicon support and having an electric potential forming the accumulation value, wherein the certain values of the received analog pulses are accumulated in the accumulation value, and wherein the discharge pulse is emitted according to the accumulation value.
