San Jose, California-based Cypress Semiconductor Corp heaves a sigh of relief as it reports that it and Fujitsu Ltd have obtained all federal regulatory approvals necessary to complete the proposed sale of Sparc designer and marketer Ross Technology Inc to Fujitsu’s computer operation; the transaction, which is effective as of the close of Cypress’ second quarter, is subject to final approval of definitive agreements by Cypress and Fujitsu boards of directors, but the regulatory hurdle was the big one because Uncle Sam ruled a few years back that Fujitsu could not buy Fairchild Semiconductor, which ended up being dismembered, with bits going to National Semiconductor Corp and the Clipper RISC business to Intergraph Corp of Huntsville.
