Emerging research memory and logic technologies

The purpose of this article is to introduce a set of technology relevance or evaluation criteria and, based on these criteria, to offer a critical assessment of those technology entries for memory and logic being considered for post CMOS-scaling information processing. Additionally, charge-based nanoelectronic devices are discussed in this article separately from those approaches proposing use of a new means for data representation or "state variable." This separate discussion addresses an important question related to new charge-based information-processing approaches concerning the fundamental limits of an elemental switch (size, energy, speed, etc.).
