The graphic for this post (click to enlarge), supplied by ASML, the semiconductor industry’s leading lithography tool supplier, illustrates the challenge of migrating from one process node to the next. Across the bottom, on the X-axis, are representative process nodes ranging from “2D-45”, or two-dimensional (planar) 45nm NAND, to “3D-5x”, or three-dimensional 5xnm NAND. Below these numbers are the year of volume production.
The vertical axis, labeled “Tolerance” represents the minimum Continue reading
Samsung’s release tells us that the SuperMUC, the most powerful supercomputer system in Europe, is an IBM System x iDataPlex dx360 M4 server built using over 18,000 Intel Xeon CPUs and over 80,000 4GB DRAM modules from Samsung. (Simple math makes this out to be 82,944 modules.)
That looks like a lot of silicon! Let’s see how much that might be.
A 4GB parity DRAM module would use nine 4Gb DRAM chips, which Samsung appears to Continue reading
