Abstract:Capacitorless two‐transistor (2T0C) dynamic random‐access memory (DRAM) cells comprising oxide thin‐film transistors (TFTs) show potential as low‐power and high‐density DRAM cells; however, the multiply–accumulate (MAC) operation using these cells is not yet realized. In this study, 2T0C DRAM cells comprising amorphous indium–tin–gallium–zinc oxide TFTs are fabricated for MAC operations. In a 2T0C DRAM cell, one transistor acts as a write transistor and the other as a read transistor, whose gate capacitance co… Show more
