We report on the first demonstration of multilevel multiply accumulation operations in 2TlC cell arrays based on amorphous IGZO TFTs for efficient analog in memory compute (AiMC) implementation. Device designs for the read and write transistors to meet the target specifications are discussed and implemented. Multilevel operations are realized thanks to the long retention time enabled by the ultra-low offcurrent (
