Sophgo drew consideration after a chip discovered on Huawei’s Ascend 910B multi-chip AI system matched one it ordered from Taiwan Semiconductor Manufacturing Co.

Huawei was positioned on the Entity Listing in 2019 and is now on the heart of China’s AI chip ambitions.

Sophgo is amongst quite a few firms which have been punished for serving to Huawei. Late final yr, the Commerce Division added different firms seen as a part of Huawei’s shadow community to the restricted commerce record.

The brand new guidelines observe curbs the U.S. positioned on TSMC after discovery of its chip in Huawei’s Ascend 910B multi-chip system. As Reuters solely reported, the U.S. in November ordered TSMC to halt shipments of sure superior chips.

ADDING NEW CONTROLS

The newest regulation provides new controls for chip factories and packaging firms looking for to export sure chips, constructing on earlier measures geared toward hampering China’s entry to chips that might assist its army.
