BEOL-friendly Access Devices (AD) based on Cu-containing MIEC materials [1] [2] [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.
