A 160-kilobit molecular electronic memory patterned at [10.sup.11] bits per square centimetre

Article Abstract:

A 160,000-bit molecular electronic memory circuit is fabricated at a density of [10.sup.11] bits [cm.sup.-2], which is roughly analogous to the dimensions of a dynamic random access memory circuit projected to be available by 2020. A monolayer of bistable, [2]rotaxane molecules have served as the data storage elements and although the circuit has many defects, those defects can be readily identified through electronic testing and isolated using software coding.

Accurate multiplex gene synthesis from programmable DNA microchips

Article Abstract:

A microchip-based technology is described for multiplex gene synthesis. Groups of thousands of 'construction' oligonucleotides and tagged complementary 'selection' oligonucleotides are synthesized on photo-programmable microfluidic chips, that are released, amplified and selected by hybridation to reduce synthesis errors.

Programmable computing with a single magnetoresistive element

Article Abstract:

A simple hardware concept is described for a programmable logic element that is based on a single magnetic random access memory (MRAM) cell. The computational performance can be improved if the logic gate is additionally capable of storing the output.
