Abstract
We fabricated an indium gallium zinc oxide (IGZO) charge trap flash (CTF) device for logic-in-memory (LIM) applications. Initially, the nonvolatile memory characteristics of the IGZO CTF device were investigated under charge trapping and detrapping states in 104 s retention tests. Next, we constructed a common-source amplifier circuit containing the IGZO CTF device and demonstrated various input-output signal relationships by modulating the memory state of the device. Finally, we used interconnected IGZO CTF devices to demonstrate reconfigurable logic functions. Using series- and parallel-connected IGZO CTF devices, we developed 2-input NAND and 2-input NOR gates, respectively. Our experimental results showed that the IGZO CTF device is a promising future memory device and a tool for LIM technology. © 2024 Author(s).
