Abstract:
1. A device comprising: an array of chemically-sensitive field-effect transistors (chemFETs), at least some chemFETs in the array of chemFETs comprising: a plurality of first conductive lines coupled to chemFETs in the array, wherein each first conductive line in the plurality of first conductive lines is directly connected to the first source/drain terminals of chemFETs in a column in the array; and a plurality of second conductive lines coupled to chemFETs in the array, wherein each second conductive line is directly connected to the second source/drain terminals of chemFETs in a row in the array; bias circuitry coupled to the array to apply a read bias to selected chemFETs via the first conductive lines and second conductive lines; and sense circuitry coupled to the array to sense charge coupled to the floating gates of selected chemFETs.
