By Sayantani Ghosh July 1 (Reuters) - A handful of chipmakers including Micron and AMD have signaled waning demand as red-hot inflation squeezes consumer and corporate spending, while easing a two-year global semiconductor shortage that was exacerbated by supply-chain disruptions. 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.
