1. An apparatus, comprising:
- a semiconductor chip memory array having resistive storage cells;
a comparator to compare a first word to be written into the array against a second word stored in the array at a location targeted by a write operation that will write the first word into the array; and
,circuitry to iteratively write to one or more bit locations where a difference exists between the first word and the second word with an increasing write current intensity with each successive iteration.

Abstract
An apparatus is described that includes a semiconductor chip memory array having resistive storage cells. The apparatus also includes a comparator to compare a first word to be written into the array against a second word stored in the array at the location targeted by a write operation that will write the first word into the array. The apparatus also includes circuitry to iteratively write to one or more bit locations where a difference exists between the first word and the second word with increasing write current intensity with each successive iteration.

8. An apparatus, comprising:
-
a semiconductor chip memory array having resistive storage cells; a comparator to compare a first word to be written into the array against a second word stored in the array at a location targeted by a write operation that will write the first word into the array; and
,circuitry to iteratively write to one or more bit locations where a difference exists between the first word and the second word with increasing write current intensity with each successive iteration, where, an applied write current intensity for each successive iteration is based on a percentage of storage cells that is expected to be set by the applied write current intensity. - View Dependent Claims (9, 10, 11, 12, 13, 14)
