Samsung reportedly ramps up GDDR6 supply for Tesla but halts 1d DRAM mass production plan
What happened
Samsung Electronics is reportedly increasing GDDR6 production for Tesla starting April 2026, while simultaneously halting mass production plans for its next-generation 1d DRAM due to insufficient yields. This represents a strategic reallocation of capacity within Samsung's memory portfolio, prioritizing a specific, high-demand customer over a next-gen node. Watch: Mixed supply signals; GDDR6 supply for Tesla may tighten, but broader DRAM capacity constraints could ease slightly due to the 1d DRAM delay.
