An inkjet print head includes data signal lines configured to supply inkjet control voltages and non-volatile memory cell random access addresses. The inkjet print head includes an inkjet nozzle array wherein each nozzle in the array is configured to communicate with a data signal line. Also a non-volatile attribute memory cell array is included in the inkjet print head wherein each memory cell in the array is accessed through a data signal line shared with the nozzle array.

A print element board includes: a plurality of first print elements; a plurality of second print elements; a plurality of first drive elements configured to drive the plurality of first print elements; a plurality of second drive elements configured to drive the plurality of second print elements; a drive signal generation circuit configured to generate a first drive signal and a second drive signal; and a drive signal selection circuit configured to select both or one of the first drive signal and the second drive signal based on an externally-supplied operation switching signal, and at least one of the first drive elements and at least one of the second drive elements operate based on the drive signal selected by the drive signal selection circuit.
