Samsung Begins Mass Production of 12 GB LPDDR4X for Smartphones
Samsung announced late on Wednesday that it had started volume production of 12 GB LPDDR4X-4266 memory for high-end smartphones. The chip is currently the highest-density DRAM for mobile applications. The first smartphone to use Samsung's 12 GB LPDDR4X DRAM package will be the company's own Galaxy S10+ handset formally announced last month.
Samsung's 12 GB LPDDR4X package integrates six 16 Gb memory devices featuring a 4266 MT/s data transfer rate at 1.1 Volts and produced using the company's second-generation '10nm-class' process technology (also known as 1y-nm). The 12 GB memory module is 1.1 mm tall, which is a bit higher than standard quad-die LPDDR4X packages (which are thinner than 1 mm), but Samsung has managed to incorporate the device into its latest premium smartphone.
Were the previously announced 12 GB DRAM smartphones using two packages instead of this one thick package?

Nipping this one in the bud because everyone always asks: These modules support TRR, MAC, and PARA. This means that they have all the hardware mitigation for Rowhammer built-in and usable at negligible (0.1%) performance hit. As long as Samsung picks good mitigation parameters (not all manufacturers do), rowhammer is effectively dead.
