Nearly all processors rely on some form of SRAM caching. Caches act as a high speed storage solution with very fast access times due to their strategic placement right next to the processing cores. Having fast and accessible storage can significantly increase processing performance and result in less wasted time for the cores to do their work.
At the 68th Annual IEEE International EDM conference, TSMC revealed huge problems with SRAM scaling. The company’s next node it is developing for 2023, N3B, will include the same SRAM transistor density as its predecessor N5, which is used in CPUs like AMD’s Ryzen 7000 series.
