Samsung is currently mass-producing its 9th generation V-NAND flash memory chips with 286 layers unveiled this April. According to the Korean Economic Daily, the company targets V-NAND memory chips with at least 400 stacked layers by 2026. In 2013, Samsung became the first company to introduce V-NAND chips with vertically stacked memory cells to maximize capacity. However, stacking beyond 300 levels proved to be a real challenge with the memory chips getting frequently damaged. To address this problem, Samsung is reportedly developing an improved 10th-generation V-NAND that is going to use the Bonding Vertical (BV) NAND technology. The idea is to manufacture the storage and peripheral circuits on separate layers before bonding them vertically. This is a major shift from the current Co-Packaged (CoP) technology. Samsung stated that the new method will increase the density of bits per unit area by 1.6 times (60%), thus leading to increased data speeds.
Samsung's roadmap is truly ambitious, with plans to launch the 11th generation of NAND in 2027 with an estimated 50% improvement in I/O rates, followed by 1,000-layer NAND chips by 2030. Its competitor, SK hynix, is also working on 400-layer NAND aiming to have the technology ready for mass production by the end of 2025, as we previously mentioned in August. Samsung, the current HBM market leader with a 36.9% market share have also plans for its DRAM sector intending to introduce the sixth-generation 10 nm DRAM, or 1c DRAM by the first half of 2025. Then we can expect to see Samsung's seventh-generation 1d nm (still on 10 nm) in 2026, and by 2027 the company hopes to release its first generation sub-10 nm DRAM, or 0a DRAM memory that will use a Vertical Channel Transistor (VCT) 3D structure similar to what NAND flash utilizes.
