Next-generation 3d dram approaches reality as scientists achieve 120-layer stack using advanced deposition techniques – Understanding 3D DRAM Technology
Dynamic Random Access Memory (DRAM) is a crucial component in modern computing devices, serving as the primary memory for data storage and retrieval. Traditionally, DRAM has been built in a two-dimensional structure, limiting the density and speed of the memory chips. However, the advent of 3D DRAM technology promises to revolutionize the field by stacking memory cells vertically, thereby increasing the amount of data that can be stored in a smaller footprint.
The innovative approach taken by researchers at imec and Ghent University marks a pivotal moment in this evolution. By employing advanced epitaxial techniques, the team has successfully controlled atomic strain to create a nanoscale structure that resembles a “skyscraper” of memory layers. This groundbreaking method not only enhances the potential for higher memory density but also improves the speed at which data can be accessed and processed.
