Abstract
Resistive Memory in recent year has emerged as a potential candidate in the field of Non Volatile Memory to solve the existing problems with FLASH. The operation novelty of ReRAM helps to evolve it from storage device to an effective ultra sensitive biomarker with a very simple structure and fabrication process steps. Basically as ReRAM is MIM capacitor like structure so for store data in terms of charge like DRAM is feasible effectively and at the same time capacitor as we know can be excellent for bioanalyte detection. So with same structure two purpose can be solved. Also we can see in this chapter that the biosensors with ReRAM will detect on Current -Voltage sampling method which is more efficient to detect with low sample volume. This chapter will give the readers a brief idea about the work done and ongoing research on Resistive memory as Non Volatile Memory as well as its potentiality as Biosensor.
