Acceleration of Model/Weight Programming in Memristor Crossbar Arrays

A method comprising:

• receiving a set of output vector data from an output of a memristor crossbar array, the memristor crossbar array having a number of memory elements, the crossbar array having N rows, M columns and N×M memory elements;
• receiving from a memory register a set of input vector data;
• evaluating the set of output vector data to the set of input vector data;
• determining changed data values as between the output vector data and the input vector data;
• and
• writing the changed data values to the to the memory elements of the crossbar array.

A non-transitory computer storage device storing instructions operable to cause one or more computer methods to perform operations comprising:

• receiving a set of output vector data from an output of a memristor crossbar array, the memristor crossbar array having a number of memory elements, the crossbar array having N rows, M columns and N×M memory elements;
• receiving from a memory register a set of input vector data;
• comparing the set of output vector data to the set of input vector data;
• determining changed data values as between the output vector data and the input vector data;
• and
• writing the changed data values to the to the memory elements of the crossbar array.
