Slowing SRAM Density Scaling and Its Implications for Next‑Gen Process Nodes
Problem
The industry is noticing that traditional density scaling is decelerating; the improvement from N10 to N2 is only about 20%, and the latest A14 chip delivers merely a 2.9% increase in SRAM density, raising doubts about the viability and cost‑effectiveness of Angstrom‑scale processes.
Pain points
- SRAM density growth is slowing, with only about a 2.9% improvement
- The density gain from N10 to N2 has dropped to roughly 20%
- Skepticism about the technical feasibility and cost of Angstrom‑scale processes
Questions to verify
- Did TSMC actually achieve only about a 2.9% SRAM density improvement in the A14 chip?
- When designing new products, are companies primarily constrained by SRAM density rather than logic density?
- Can Angstrom‑scale manufacturing costs remain within an acceptable range?
Evidence

Chip density increase is slowing down. Since N10, density scaling has been 60-80%. N3 to N2 is only 20%. And now N2 to A14 is also only 20%.

In simpler terms, the SRAM density improved by 2.9% (according to ChatGPT). Which is better than it sounds, because SRAM had reached a wall, in terms of density gains, and, chips can be dominated by SRAM in terms of surface area, so this can mean a lot more room for logic, even though that is also getting considerably denser.

Whatever happened to the problem of electrons just hopping around since they are areas of probability rather than particles when you get small enough
