PRINTHEAD WITH A NUMBER OF VERTICAL OXIDE MEMRISTORS HAVING A SACRIFICIAL DIELECTRIC LAYER

摘要

A printhead with a number of vertical oxide memristors having a sacrificial dielectric layer is described. The printhead includes a number of nozzles to deposit an amount of fluid onto a print medium. Each nozzle includes a firing chamber to hold the amount of fluid, an opening to dispense the amount of fluid onto the print medium, and an ejector to eject the amount of fluid through the opening. The printhead also includes a memristor array comprising a number of memristors. Each memristor includes a bottom electrode disposed on a substrate, a vertical switching oxide abutting the bottom electrode and disposed on the substrate, a sacrificial dielectric layer abutting the vertical switching oxide and disposed on the substrate, and a top electrode abutting the vertical switching oxide and disposed on the sacrificial dielectric layer.
