Zusammenfassung:A memory cell for a printhead includes a substrate with a source and a drain. The substrate further includes a channel located between the source and the drain and surrounding the drain. The drain can include a first rounded closed curved structure. The memory cell can include a floating gate and a control gate. The floating gate can include a second rounded closed curve structure located above the channel and below the control gate. The control gate is capacitively coupled to the floating gate.
