In the ongoing tech war between the US and China, the Biden administration faces pressure from lawmakers to restrict US companies involved in the development of RISC-V, a freely available chip technology widely used in China. This move could disrupt global collaboration in the tech industry. RISC-V, pronounced as “risk five,” is an open-source alternative to British semiconductor and software design company Arm Holdings’ expensive proprietary technology, and has diverse applications, from smartphone chips to advanced AI processors. US lawmakers have raised concerns about China taking advantage of the culture of open collaboration among US companies in order to bolster its own semiconductor industry. [Reuters]
