Distributed Data Storage in a Resistor Array
摘要
When we use a resistor array (crossbar) for data storage, we usually take resistors with variable conductivity as storage cells. The drift of resistor conductivities is often the case in data recording (and storage). Complicated procedures are needed to cope with this problem. It is possible to use distributed data storage systems in which the recording (change) of a storage unit involves a change of conductivity of many resistors. The paper considers an approach which uses a combination of distributed row or column data storage using weighted sums of orthogonal functions and harmonic signals-based data recording to tackle the drift of resistor states and increase the storage noise immunity.
