Reducing stray currents in molecular memory through data encoding

Much progress is being made in the fabrication of molecular devices and nanoscale circuits. Such strides have led to studies and experimental tests using these devices in non-volatile memory arrays. However, the architecture of such arrays makes it difficult to accurately determine the value of each stored bit in the memory. When reading, each bit is effected by the rest of the memory through variable numbers of 'stray current paths'. This paper presents the idea of data encoding to thwart the impacts of these stray currents. The results show that this encoding method makes each bit unique and deterministic, independent of the memory array size. Details of the encoding scheme, the hardware design, and layouts are presented throughout this work.
