    Micron Abandons 4F² DRAM for 1δ Process

    • Micron deems the 4F² DRAM architecture too difficult to engineer, opting to stick with 6F² and transition to the 1δ process.
    • The company plans to redirect saved R&D bandwidth toward conquering monolithic 3D DRAM as the ultimate goal.
    • DRAM cell geometries (e.g., 6F²) differ fundamentally from logic chip process node naming conventions.
