Evaluation of performance in vertical 1T-DRAM and planar 1T-DRAM

Yuto Norifusa, Tetsuo Endoh

Research output: Contribution to journalArticlepeer-review


The performances of the conventional planar type 1T DRAM and the Vertical type 1T DRAM are compared based on structure difference using a fully-consistent device simulator. We discuss the structural advantage of the Vertical type 1T-DRAM in comparison with the conventional planar type 1T-DRAM, and evaluate their performance in each operating mode such as write, erase, read, and hold; and discuss its cell performances such as Cell Current Margin and data retention. These results provide a useful guideline designing the high performance Vertical type 1T-DRAM cell.
