A printhead substrate, comprising an electrothermal transducer configured to heat a printing material, a first DMOS transistor configured to drive the electrothermal transducer, a MOS structure forming an anti-fuse element, a second DMOS transistor configured to write information in the anti-fuse element by causing an insulation breakdown of an insulating film of the MOS structure, and a driving unit consisted of at least one MOS transistor and configured to drive the second DMOS transistor. |
