About Key Foundry

Key Foundry, now operating as SK keyfoundry, is a South Korean contract chip manufacturer based in Cheongju. A foundry fabricates chips designed by other companies. It works on 8-inch wafers, an older and smaller format than the 12-inch wafers used for leading processors, and serves power management chips, display driver chips and microcontrollers. It is owned by SK hynix, the memory maker. The business is mature-node manufacturing for everyday electronics rather than cutting-edge compute silicon.

What Key Foundry 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.
