HBM is the DRAM industry’s attempt to short-circuit the slowing pace of Moore’s Law by using 3D chip-packaging technology. Each HBM chip is made up of as many as 12 thinned-down DRAM chips called dies. Each die contains a number of vertical connections called through-silicon vias. The dies are piled atop each other and connected by arrays of microscopic solder balls aligned to the TSVs. This DRAM tower—well, at about 750 micrometers thick, it’s more of a brutalist office block than a tower—is then stacked atop what’s called the base die, which shuttles bits between the memory dies and the proc
How Will the Tech Industry Handle the DRAM Shortage?… Future DRAM supply and technology “There are two ways to address supply issues with DRAM: with innovation or with building more fabs,” explains Mina Kim , an economist with Mkecon Insights. “As DRAM scaling has become more difficult, the industry has turned to advanced packaging… which is just usin… …
… One emerging approach places select periphery functions beneath the DRAM array by bonding two wafers — one optimized for the DRAM cells and the other for CMOS logic — using multiple wiring layers. …
