Abstract

The electronics industry is composed of three major components: computing (logic and memory), data storage, and communications. One of the most important limitations of computing devices is the ever-increasing power consumption required by higher processing speeds. One means of reducing the power needed is the development of multi-core processors. Such processors, however, demand much larger memories so that the proportion of a silicon chip dedicated to memory will increase from typical values today of ~60%–70% to perhaps 90% in a few years’ time. * The size and consequent cost of such chips could be significantly reduced by the development of a very high density and high-performance memory, if this can be done itself at a sufficiently low cost.
