SK Hynix ogłasza dostępność układów DDR4 16 Gb, do 256 GB DIMM



Sk Hynix has added to its product catalog single-die 16 Gb DDR4 memory chips, which should enable a two-fold increase in maximum memory capacity per single DIMM. This allows SK Hynix to sell same-capacity chips with fewer memory semiconductor dies, due to the increase in storage density, and to increase maximum memory capacity at the same memory die populations as before. The benefits are lower power consumption (due to the reduced number of memory dies to power), and the possibility of putting together either dual-ranked 64 GB modules, quad-ranked 128 GB LRDIMMs and octal-ranked 256 GB LRDIMMs. That last part is the most important: theoretically, the maximum amount of memory on top Intel or AMD server platforms could double, which could enable up to 4 TB RAM in EPYC systems, for example. And as memory-hungry as big data applications have become, there's ever need for higher memory capacity.

Układy 16 GB DDR4 SK Hynix są zorganizowane jako 1Gx16 i 2Gx8 i są dostarczane odpowiednio w pakietach FBGA96 i FBGA78. Obecne prędkości gęstości 16 Gb wynoszą w trybach DDR4-2133 CL15 lub DDR4-2400 CL17 przy 1,2 V. Plany SK Hynix zwiększają dostępne częstotliwości w trzecim kwartale tego roku, dodając DDR4-2666 CL19 do składu. Sources: SK Hynix, via AnandTech
