Samsung Electronics is reportedly nearing the final stage of qualification tests for its HBM4 memory chips with Nvidia, with a December decision that could mark one of the company’s most significant comebacks in the high-end memory market in recent years, according to South Korean outlet Newdaily. At the same time, reports from ZDNet Korea and The Korea Herald say Samsung has overhauled its memory development organization to stabilize HBM production and challenge SK Hynix’s lead.
