As the global leader and the most technologically sophisticated semiconductor manufacturer, TSMC has been grappling with a stagnation in SRAM (Static Random-Access Memory) scaling technology for several years. Since the initiation of mass production for the 5nm process in 2020, the area of the 6T SRAM memory cell has plateaued at around 0.021 square micrometers. Meanwhile, the transistor density of logic devices has consistently climbed, yet memory technology has struggled to keep up with this pace. Nevertheless, this impasse is anticipated to be resolved with the upcoming launch of the A14 node, which is slated for production in 2028.
