Cirrus, Lucent Adjust Chip-Buying Pact

Fremont-based Cirrus Logic Inc. said it and Lucent Technologies Inc. agreed to change the percentage of computer chip wafers that each company must buy from their jointly owned semiconductor plant. Chip maker Cirrus Logic and telecommunications equipment maker Lucent are partners in Cirent Semiconducter, a manufacturing plant in Orlando, Fla. The plant produces chips that are used in computers, cellular phones, pagers and other electronic devices. Cirrus said it will decrease the percentage of semiconductor wafer production that it buys from Cirent to 25% from 50%, while New Jersey-based Lucent will increase its purchase obligation to 75% from 50%.
