Samsung stacks 512GB onto a single stick of DDR5 RAM. This isn't an SSD guys

Samsung has announced a major breakthrough in DDR5 SDRAM design by producing a 512GB DDR5 DIMM. Not only does that make it the most capacious stick of RAM in the world, but Samsung also managed to win first in the speed stakes as well, as the new sticks manage a ridiculous 7,200Mbps. 

This has been made possible thanks to Samsung’s TSV tech (which confusingly stands for Through Silicon Via), that allows it to stack eight memory chips on top of each other. It also uses High-K Metal Gate (HKMG) materials, which is something traditionally reserved for logic semiconductors, not memory. It’s used here as a replacement for the usual insulation layer because, as densities have increased, legacy insulation layers have got too thin, leading to higher leakage current.
