Chiplets: The Future of Semiconductor Innovation

Chiplet technology is transforming the semiconductor industry by enabling modular, high-performance, and cost-effective processor designs. Instead of manufacturing a monolithic system-on-chip (SoC), chiplets allow manufacturers to integrate multiple specialized modules onto a single package, improving scalability, power efficiency, and customization.
