Claim Text:
1. An apparatus, comprising: at least one resistance change memory (RCM) cell; three or more pairs of electrical contacts coupled to the at least one RCM cell, a first portion of the pairs being arranged laterally to one another in a first grouping and a second opposing portion of the pairs being arranged laterally to one another in a second grouping; and a memory cell material disposed between opposing sides of the pairs of the three or more electrical contacts, the memory cell material being configured to form a conductive pathway between one or more of the pairs, a resistance state of the RCM cell being based at least partially on a lateral size of the conductive pathway formed within the memory cell material between the pairs, each pair of the three or more pairs being configured to be accessed individually, a number of permutations for programming, erase, or read operations of the at least one RCM cell is to increase approximately according to a power-law relationship based on a number of conductive pathways formed within the RCM cell, the power-law relationship relating the number of permutations, N
