Our mission is to be the trusted technology and capacity provider of the global logic IC industry for years to come." Tom's Hardware describes the statement as essentially a denial of The Information's November 6 report that TSMC was charting plans to make 3D DRAM at Nvidia's request. Note the caveat: the statement does not directly address the specific development program described in the report; TSMC's line to Reuters on Friday, November 6, remained that it does not comment on market rumors, while restating its focus on its core foundry business. The Information's sources maintain that preliminary plans were drafted under Hsu Kuo-chin, TSMC's vice president for advanced packaging.

Why it matters: This is a direct follow-up and correction to the "TSMC may develop 3D DRAM at Nvidia's request" story reported earlier. If TSMC is indeed staying out of memory, the shortage will remain dominated by Samsung, SK Hynix and Micron, and the "fourth supplier" prospect raised in the 22:38 report does not hold for now; but since TSMC has not denied the specific program point by point, any formal investment decision or further statement still bears watching.
