초록
In this paper, we investigated the threshold voltage (VT) dispersion and on-current in poly-GaAs used for a channel material in 3D NAND flash memory. Using simulation, stings of NAND flash memory with 12, 24, 36, and 48 cells were implemented and electrical properties were extracted. It is revealed that the on-current in poly-GaAs channel is larger than in poly-Si channel due to the difference in mobility. In addition, the VT dispersion tends to decrease as the numbers of stacked layers increase in case of poly-GaAs channel.
