IEDM 2022: Did We Just Witness the Death of SRAM?

There is a lot of benefit for scaling SRAM, because it makes up a large fraction of chip area on a lot of designs that use leading edge nodes (e.g., CPUs), and chip area ~= manufacturing cost for high volume products.

SRAM cells are constrained by certain features that are not able to shrink much https://semiwiki.com/forum/index.php?threads/sram-cell-scali... the logical schematic of an SRAM does not show anything about how a real cell is physically constructed. Foundries and high end design companies have teams doing SRAM design.

Yep, this is also why the claim in this article title might just be a bit overstated. There's a mention that TSMC will likely announce optimized SRAM cell designs for N3-like nodes at some point, and these designs can be expected to involve some scaling.

The mention is that Wikichip expect optimized SRAM cells but there's nothing to support this. I'm not so sure given the problem they've had so far.
