TSMC is developing a new in-memory compute technology that integrates memory directly into advanced logic chips. This approach, presented at the 2025 VLSI Symposium, uses a 1T1C cell built into the chip's interconnect layers to create a low-power, low-latency cache. The technology demonstrated fast read/write speeds and high endurance, positioning it as a denser alternative to SRAM for processor caches. Additionally, TSMC is reportedly considering manufacturing 3D DRAM at NVIDIA's request to address AI-driven memory shortages, which would place them in direct competition with existing DRAM manufacturers. AI
