Abstract
A fluid ejection device includes one or more digital data storage arrays having plural EPROM cells. A method for affirming performance adequacy of EPROM cells in the one or more arrays includes the steps of identifying a reference cell in each array, measuring a selected performance criterion for the reference cells, obtaining a reference criterion value, and evaluating the actual performance of at least one cell in each array with respect to the reference criterion value.
