Inkjet head chip identification circuit

An inkjet head chip identification circuit, comprising:

• an identification circuit matching with a printer, so that the printer provides an inkjet head chip with required information according to a matching result,
• wherein the identification circuit comprises a plurality of memory units, and the memory units are arranged in an array structure,
• wherein the plurality of memory units further comprise a first transistor, a third transistor, a fuse or a combination thereof, the first transistor is a MOSFET-Anti-Fuse, and the third transistor is an erasable programmable read only memory (EPROM), wherein a data signal of each memory unit is controlled and read by burning the first transistor, the third transistor and the fuse or not, wherein the first transistor, the third transistor and the fuse are formed on the same inkjet head chip.
