Samsung is now shipping HBM4 memory, will sample HBM4E to customers later this year‎

Samsung has already delivered the first shipments of HBM4 memory to its customers and announced that it has begun mass production of the new standard. HBM4 chips are fabbed on a 6th generation of a 10nm-class DRAM process called “1c”. Note that DRAM isn’t like a CPU core, so the nodes aren’t comparable. The HBM4 products also use a 4nm logic base die for higher performance. To put some numbers to it, HBM4 can deliver speeds of 11.7Gbps – per pin! This surpasses the industry standard, which is set at 8Gbps, by 46%. Since there are 2,048 pins the total bandwidth is a massive 3.3 terabytes...
