Taiwan Semiconductor Manufacturing Co. has allegedly cut off shipments to Chinese chip designer Sophgo over allegations it was attempting to supply components to Huawei in violation of US sanctions.
The report comes roughly a week after TSMC alerted US officials to what they believed was an attempt by Huawei to subvert US export controls on advanced manufacturing technologies and AI accelerators through the use of proxy companies.
TSMC raised the alarm after a customer placed orders for a chip closely resembling that of Huawei's Ascend 910B, a high-end AI accelerator aimed at AI training and inference workloads. According to Reuters, which cited two people familiar with the matter, the company in question was Sophgo.
Sophgo, which designs chips based on the open RISC-V instruction set architecture, on Sunday issued a statement denying these reports.
"The investigation of the US Commerce Department on possible TSMC and Huawei link is not related to Sophgo and its product. Sophgo has never engaged in any direct or indirect business relationship with Huawei," the statement reads.
