Foundry Boundaries and AI Memory Pressures: Analyzing TSMC’s Rebuttal to the 3D DRAM Rumor

TSMC Is Working On A BEOL Memory That Can Leverage The Larger Footprint Of The Processor Die To Its Advantage, Even As It Issues A Circuitous Denial On 3D DRAM Development

When news first emerged earlier this week that TSMC was apparently entering the 3D DRAM business, it was trumpeted as a definitive proof that the memory sphere had finally graduated beyond its dreaded commodity status. Then, TSMC dashed that budding euphoria by issuing a rambling denial. And yet, the very wording of that statement gives us cause to continue to expect some movement on this front, especially as the world's largest contract chip ma…
