摘要:
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.

摘要:
A fluid ejection device having a first fluid feed source having a first fluid feed source edge in communication with a substrate surface, first firing resistors disposed along the first fluid feed source and configured to respond to a first current to heat fluid provided by the first fluid feed source, and a reference conductor. The reference conductor is configured to conduct the first current from the first firing resistors, wherein the reference conductor is disposed between the first fluid feed source edge and the first firing resistors.

A device includes a substrate, a first gate, a second gate, and a third gate. The substrate has a first active region and a second active region. The first gate is configured in a first loop structure around the first active region. The second gate is configured in a second loop structure around the second active region, and the third gate is configured in a third loop structure around the first gate and the second gate.
摘要:
A fluid ejection device comprising an identification line adapted to receive a program signal and a read signal and identification cells electrically coupled to the identification line. Each of the identification cells comprises a memory circuit and a memory element. The memory circuit is adapted to receive and respond to signals in order to selectively store a value in the memory circuit, which determines whether the identification cell is responsive to signals received on the identification line.

A fluid ejection device includes a first fire line adapted to conduct a first energy signal having energy pulses, a second fire line adapted to conduct a second energy signal having energy pulses, a first address generator configured to provide first address signals, a second address generator configured to provide second address signals, first drop generators and second drop generators. The first drop generators are electrically coupled to the first fire line and configured to respond to the first energy signal to eject fluid based on the first address signals. The second drop generators are electrically coupled to the second fire line and configured to respond to the second energy signal to eject fluid based on the second address signals.
