ItInsightsWorld General Report: DRAM Cell Scaling Search Ends Without the Smaller Target

A memory cell is not just a logic switch. In DRAM, each unit brings together one transistor and one capacitor, and that two-part construction changes the scaling problem.

Where the search landed

• Micron put over two decades into the smaller layout before changing course.
• The established geometry, 6F², remains the practical path.
• The alternative, 4F², had been treated as the 'holy grail' of cell density work.

What the reported density case was

The smaller geometry attracted attention because it promised a theoretical 33% improvement. After over two decades, the company now describes its stance as staying with 6F² for the foreseeable future rather than continuing the chase.
