摘要
We propose a surrounding gate. MOSFET with vertical channel (SGVC cell) as a 1T DRAM cell. To confirm the memory operation of the SGVC cell, we simulated its memory effect and fabricated the highly scalable SGVC cell. According to simulation and measurement results, the SGVC cell can operate as a 1T DRAM having-a sufficiently large sensing margin. Also, due to its vertical channel structure and common source architecture, it can readily be made into a 4F(2) cell array.
