SEMICONDUCTOR BIOSENSOR AND CONTROL METHOD THEREOF

摘要

A semiconductor biosensor and a control method thereof are disclosed for enhancing performance of semiconductor biosensor and the reducing price of medical healthcare chip. An embodiment of the semiconductor biosensor includes a central reaction unit (200). The central reaction unit (200) comprises a plurality of semiconductor conducting wires (6); a common source (2), wherein one end of each conducting wire (6) is connected to the common source (2); a plurality of non-volatile memory type transistors (31) respectively connected to another end of each conducting wire (6); a plurality of sense-amplifiers (9) respectively connected to the said non-volatile memory type transistors (31); a bit line controller (22) analyzing signals sensed by the said sense-amplifiers (9) and managing the operation of the said non-volatile memory type transistors (31); an oxide film (1) wrapping or covering the said conducting wires (6), and a plurality of receptors (8) fixed on a surface of the said oxide film (1).
