Chip manufacturer Advanced Micro Devices Inc., based in Sunnyvale, Calif., is seeking 90,000 sf of office space in Austin to house Alchemy Semiconductor, which AMD recently purchased. The facility will be home to Personal Connectivity Solutions, a newly formed AMD division focused on non-PC product devices. Alchemy’s lease on 20,000 sf in Austin expires at the end of April. Alchemy develops and markets microprocessors.
