By Sayantani Ghosh July 1 (Reuters) - A handful of companies including chipmakers Micron and AMD are signalling an easing in the two-year long global shortage of semiconductor chips as rising inflation and cooling economies squeeze consumer and corporate spending. Advanced Micro Devices Inc AMD.O flagged last month a slowdown in PC sales this year after two years of strong demand. TSMC 2330.TW, the world's largest contract chipmaker, has seen its major clients cut chip orders for the rest of 2022, Taiwanese daily Digitimes said on Friday, citing industry sources.
