Abstract
The present disclosure relates to an apparatus for a memristor crossbar array. The apparatus comprises an adjustment circuit configured for receiving a current that is output by the array at an actual operating condition of the array. The apparatus further comprises a calibration circuit configured for determining a measured or modelled variation of output currents of the array at the actual operating condition with respect to a reference operating condition, wherein the adjustment circuit is configured to adjust the output current by the variation.
Claims19
An apparatus for a memristor crossbar array, the apparatus comprising:
- a first circuit configured for receiving a current that is output by an array at an actual operating condition of the array;
- and
- a second circuit configured for determining a measured or modeled variation of output currents of the array at the actual operating condition with respect to a reference operating condition, wherein the first circuit is configured to adjust the output current by the variation,
- the variation determined as a value of a compensation function corresponding to a measured temperature associated with the actual operating condition.
A memory circuit comprising an apparatus and a memristor crossbar array, wherein the apparatus comprises:
- a first circuit configured for receiving a current that is output by an array at a current operating condition of the array;
- and
- a second circuit configured for providing a reference current at a reference operating condition of the array, and for determining a variation to the reference current at the current operating condition, wherein the first circuit is configured to adjust the output current by the variation,
- the variation determined as a value of a compensation function corresponding to a measured temperature associated with the actual operating condition.
A method for a memristor crossbar array comprising:
- receiving a current that is output by the array at an actual operating condition of the array;
- measuring or modeling a variation of output currents of the array at the actual operating condition with respect to a reference operating condition;
- and
- adjusting the output current by the variation,
- the variation determined as a value of a compensation function corresponding to a measured temperature associated with the actual operating condition.
