Micron’s 1α DRAM node represents the company’s fourth-generation 10 nm-class process technology, delivering a major leap in memory density, power efficiency, and manufacturing ingenuity without relying on extreme ultraviolet (EUV) lithography at the time of its introduction. This node, also called 1-alpha or D1α, marked a pivotal point in DRAM scaling when conventional photolithography hit… Read More Micron’s 1α (1-alpha) DRAM Node: The Fourth-Generation 10 nm-Class Process Technology

Micron (and the broader DRAM industry) moved away from literal nanometer labels toward alphanumeric designations once feature sizes entered the teens of nanometers. The half-pitch of the active area in the memory cell array serves as the primary reference metric. The 10 nm-class spans roughly 10–19 nm half-pitch. Micron’s sequence begins with 1x (first generation),… Read More Micron 1y DRAM Node: The company’s second-Generation 10 nm-Class process Technology

Micron’s 1x DRAM node marked the company’s entry into the 10 nm-class era of memory manufacturing. It was the first-generation process in that class (typically corresponding to a half-pitch in the 17–19 nm range), succeeding earlier 20 nm-class nodes such as 2y nm and enabling smaller dies, higher bit density, and improved cost-per-bit for DDR4… Read More Micron 1x DRAM Node: The company’s first-Generation 10 nm-Class process Technology
