TSMC A14 Node to Break Eight Years of SRAM Scaling Stagnation

What happened

Since the launch of TSMC's N5 5 nm process in 2020, the size of the SRAM 6T bitcell has remained around 0.021 µm², with logic transistor density increasing but memory not seeing similar advancements. With the A14 node, the 6T SRAM bitcell is expected to shrink significantly to 0.017 µm², a 19% reduction, with production set for 2028. TSMC is currently conducting pilot production to assess the viability of the node, enabling customers to evaluate how their designs will perform in TSMC's production environment; the progress of A14 production is reported as promising, with timelines advancing due to early successes. If pilot production continues smoothly without major yield or production issues, risk production is set to commence in 2027, followed by high-volume manufacturing in 2028; if no significant challenges arise next year, TSMC may even accelerate the production schedule by a few months.
