Abstract
Computing apparatus (e.g., a neural network) advantageously comprises a programmable resistor body comprising typically a multiplicity of resistors R.sub.ij. The resistance of any given R.sub.ij is changeable from a relatively high resistance to a lower resistance by application of an appropriate electrical signal, and can be reset to a higher resistance by application of an appropriate signal of reverse polarity. Exemplarily, a programmable resistor body comprises a thin layer of bismuth oxide or strontium barium niobate.
