TDK Semi Changes Name After Sale

Irvine-based TDK Semiconductor Corp. has changed its name to Teridian Semiconductor Corp. after being sold by Japan’s TDK Corp. earlier this year.

In April, San Francisco private equity firm Golden Gate Capital LP bought what’s now Teridian for undisclosed terms.

TDK had considered spinning off the chip designer in a public offering in 2002. The company even hired investment banks for the offering, which could have raised $100 million.

But TDK pulled back amid a soft market for chip stocks.

The name change is part of the company’s move away from TDK with the sale to Golden Gate.

The move “represents an important step in our evolution” said Gerald Fitch, Teridian’s chief executive.

Teridian designs chips for networking gear, modems, smart card readers and other devices.
