TSMC’s 3nm Node: No SRAM Scaling Implies More Expensive CPUs and GPUs

As for the brand new manufacturing node, we can expect better performance, lower power consumption and higher transistor density. But while logic circuits have scaled well on recent process technologies, SRAM cells have lagged behind and seem to have nearly stopped scaling at TSMC’s 3nm-class production node. This is a big problem for future CPUs, GPUs and SoCs, which are likely to be more expensive due to the slow scaling of SRAM cell area.

Slow SRAM scaling

When TSMC officially introduced its N3 manufacturing technology earlier this year, it said the new node would offer 1.6x and 1.7x improvements in logic density compared to its N5 (5nm class) process. What it didn’t reveal is that his SRAM cells of the new technology scale very little compared to his N5. wiki chipinformation taken from a TSMC paper published at the International Electron Devices Meeting (IEDM).
