Claim 0:
1. A system for implementing a neural network, the system comprising:
a crosspoint array comprising a plurality of nodes, each node representing a connection between neurons of the neural network, and each node storing a weight assigned to the node, the crosspoint array comprising:
a crosspoint device at each node, the crosspoint device comprising:
a counter comprising a plurality of single bit counters, states of the single bit counters representing the weight to be stored at the crosspoint device; and
a resistor device comprising a plurality of resistive circuits, each resistive circuit associated with a respective single bit counter from the plurality of single bit counters, the resistive circuits are activated or deactivated according to a state of the associated single bit counter, and an electrical conductance of the resistor device being adjusted based at least in part on the resistive circuits that are activated; and

a global controller configured to adjust values stored at each crosspoint device in the crosspoint array.
