What GigaDevice works on
Custom Silicon
Custom silicon means a company designs its own chips for its own products or data centers instead of buying standard parts. The chip is made by a foundry such as TSMC, but the design belongs to the customer.
Memory & Storage
Memory and storage hold the data that processors work on. Memory such as DRAM is fast and loses its contents when power is removed. Storage such as flash (NAND) is slower, cheaper per bit and keeps data without power.
CPUs & RISC-V
A CPU, or central processing unit, is the general-purpose chip that runs a computer. It reads instructions, does arithmetic and logic, and decides what happens next. Every phone, laptop and server has at least one.
