A neuromorphic memory system including neuromorphic memory arrays. Each neuromorphic memory array includes rows and columns of neuromorphic memory cells. A column of postsynaptic circuits is electrically coupled to postsynaptic spike timing dependent plasticity (STDP) lines. Each postsynaptic STDP line is coupled to a row of neuromorphic memory cells. A column of summing circuits is electrically coupled to postsynaptic leaky integrate and fire (LIF) lines. Each postsynaptic LIF line is coupled to the row of neuromorphic memory cells at a respective memory array. Each summing circuit provides a sum of signals from the postsynaptic LIF lines to a respective postsynaptic circuit.
