1. A method of generating neuron spiking pulses in a neuromorphic system, comprising:
- floating one or more selected bit lines connected to target cells, the target cells having a first state, from among a plurality of memory cells arranged at intersections of a plurality of word lines and a plurality of bit lines; and
stepwisely increasing voltages applied to unselected word lines connected to unselected cells, the unselected cells having a second state, from among memory cells connected to the one or more selected bit lines other than the target cells having the first state.

14. A neuromorphic system implementing method comprising:
-
floating one or more selected bit lines connected to target cells, the target cells having a first state, from among a plurality of memory cells arranged at intersections of a plurality of word lines and a plurality of bit lines; stepwisely increasing voltages applied to unselected word lines connected to unselected cells, the unselected cells having a second state, from among cells connected to the one or more selected bit lines other than the target cells having the first state, to generate neuron spiking pulses; and providing first and second neuron spiking pulses selected from the neuron spiking pulses to a synaptic circuit including first and second memory cells with a time interval, to implement an STDP (Spike-Timing Dependent Plasticity) algorithm. - View Dependent Claims (15, 16)
