Ross Technology Integrated Circuits

Ross Technology produced high performance microprocessors using the SPARC (Scalable Processor ARChitecture) architecture until 1998 when it was closed down. The Ross manufacturing division was resurrected as BridgePoint Technical Manufacturing (backed by Fujitsu and Cypress Semiconductor) to focus on providing back end semiconductor services. The company apparently is doing business now as Criteria Labs.
