Datacenter & Cloud Sector
Datacenters form the backbone of the digital economy, hosting cloud services, AI training clusters, enterprise workloads, and storage platforms. They are among the largest and most energy-intensive consumers of semiconductors, relying on CPUs, GPUs, accelerators, memory, storage controllers, networking chips, and power management ICs. The datacenter sector is strategically important, serving hyperscalers, enterprises, governments, and colocation providers worldwide.
Semiconductor Roles in Datacenters
- Compute: Server CPUs (x86, ARM, RISC-V), GPUs, AI accelerators, FPGAs, and DPUs for diverse workloads.
- Memory: DDR5 DIMMs, HBM3, persistent memory (CXL), and LPDDR for low-power server variants.
- Storage: NVMe controllers, PCIe switch chips, NAND flash, SCM, and RAID processors for large-scale storage.
- Networking: Ethernet, InfiniBand, optical interconnects, and DPUs for low-latency, high-bandwidth data movement.
- Security: Hardware roots of trust, TPM modules, crypto accelerators, and enclave chips for secure cloud operations.
- Power & Cooling: VRMs, GaN/SiC power devices, and thermal management sensors to improve datacenter efficiency.
