Potato Semiconductor (PotatoSemi) – Active Components

Potato Semiconductor Corporation is a fabless IC design house which locates in San Jose, California. Potato Semiconductor (PotatoSemi) Corporation dedicates to developing chip to chip IO interface solution for high speed integrated circuits. Potato Semiconductor focuses on GHz 74 logic, clock buffer, IO translator, bus switch & customized IO interface.

With powerful leading technology in IO interface, logic cells & unique design rule, Potato Semiconductor can improve most of existing standard logic chips into higher speed ones. The chips will become much more reliable, with much less noise and much higher operating frequency than the same devices from other Semiconductor companies. Take a look at Potato Semiconductor’s products and do the comparison yourself.
When you compare them apple to apple, you will find out that our chips can run much faster with much higher frequency then the others.
