Micron has launched its latest form of DRAM, which is also now in volume production. It is based on the company's 1-alpha (1α, or fourth-generation) 10 nanometer (nm) node, and also incorporates 176-layer NAND for the first time. Micron asserts that has up to 40% more memory cells, and is up to 15% more power-efficient, than its predecessor.
