Samsung Announces 50nm DRAM Chip
An industry first, Samsung has developed a new 50nm DRAM chip, which will increase production efficiency by 55% over their 60nm chip. As DigiTimes reports, the new DDR2 chip has quite a bit of new technology in it, including a multi-layered dielectric layer, 3D transistor design, and can be adapted to various types of memory such as graphics and mobile DRAM.
"Furthermore, Samsung's proprietary RCAT (recess channel array transistor) technology also has been adapted to work well with Samsung's 50nm DRAM process. The RCAT, which effectively doubles the refresh term of DRAM, is a critical technology supporting higher scalability for DRAM regardless of chip size - a key feature for enabling circuitry beyond 50nms."
