Abstract: An integrated circuit (IC) erasable programmable read-only memory (EPROM) structure for a thermal inkjet printhead includes: a fire line to provide fire line data; a select line to provide selecting data; a firing cell coupled to the fire line; an EPROM cell coupled to the fire line; a selector cell coupled to the select line, the firing cell and the EPROM cell; and a data switching circuit to provide address data to the firing cell or the EPROM cell. The data switching circuit and the selector cell selectively enable transfer of the fire line data from the fire line to the firing cell or the EPROM cell as a function of state of the selecting data on the select line and the address data from the data switching circuit.
