1. An apparatus, comprising:
a chemically-sensitive field effect transistor (chemFET) sensor device comprising:
an array of reaction regions;
at least two chemFET sensors coupled to each reaction region of the array of reaction regions, wherein each chemFET sensor of the at least two chemFET sensors comprises a chemFET and a row select transistor; and
a floating gate common to the at least two chemFET sensors and in communication with each respective reaction region;
a row select circuit for biasing each row select transistor of each chemFET sensor of the at least two chemFET sensors for each reaction region in the array of reaction regions;
a column output circuit for coupling each chemFET of the at the least two chemFET sensors for each reaction region in the array of reaction regions to a respective column line in response to biasing each respective row select transistor; and
an array controller comprising memory for storage of data and software applications, and a processor for accessing data and executing applications.
