Abstract
BEOL-friendly Access Devices (AD) based on Cu-containing MIEC materials [1-3] are shown to scale to the <;30nm CDs and <;12nm thicknesses found in advanced technology nodes. Switching speeds at the high (>100uA) currents of NVM writes can reach 15ns; NVM reads at typical (~5uA) current levels can be ≪1usec.
