Abstract: A technique for measuring the resistance of a resistive element 4 in the presence of a series diode is provided. By supplying three different currents I1, I2, I3 and measuring corresponding voltages V1, V2, V3 across the resistive element and diode, the voltages can be combined to at least partially eliminate an error in the measured resistance of the resistive element caused by a voltage drop across the diode. A technique for current control in an array of resistive elements is also described in which a column of resistive elements is provided with two or more current sources switched so that while one current source is providing current to the column line corresponding to a selected resistive element, another current source has its amount of current adjusted.

Abstract: Data storage is provided using double-stranded nucleic acid molecules provided on a thermal control device comprising a plurality of sites and temperature control circuitry to independently control a temperature of each of the plurality of sites. The temperature control circuitry, controls the site temperatures to provide a different temperature at a target site compared to other sites of the plurality of sites. The different temperatures at the target site and the other sites provide a greater probability of a read or write operation acting on the target site compared to the other sites. The temperature-based addressing helps to increase physical storage density.
