Abstract:
For the past decades, the density of DRAM has been remarkably increased by making access transistors and capacitors smaller in size per unit area. However, shrinking devices far beyond the 10 nm process node increasingly poses process and reliability challenges. As Flash technology made a pivotal and successful innovation via 3D NAND, DRAM technology may also adopt vertical stacking memory cells. Vertically stacked DRAM (VS-DRAM) continues to increase bit density on a die by increasing the number of layers along with reducing the size of the transistor. In this seminar, the opportunities and challenges of VS-DRAM are discussed.
