“To effect x” means “to bring about x”. It’s an action that brings x into existence or causes x to happen. “To affect x” means “to impact x” or “to bear on x”. It’s an action that has an effect [sic] on an existing x.

Clearly, “affected” is meant above (SoCs with on-die memory are not impacted); “effected” doesn’t make sense in the context (SoCs with on-die memory are not brought about). Prices can be affected just as well as people.
