Worldwide chip sales fell 28.6 percent in January compared to a year ago, and flash memory chip maker Spansion has filed for bankruptcy protection. Those are a couple of headlines that show just how grim the economic meltdown has become for the semiconductor industry.

The Semiconductor Industry Assocation said that chip sales were $15.3 billion, down from $21.5 billion a year ago. The January figure is down 11.9 percent from December’s sales of $17.4 billion. George Scalise, president of the industry trade group, said that Januaryis historically a weak month but this year it suffered from the erosion of consumer confidence and sales declined across the board.

Demand weakened for key industry sectors such as personal computers, cell phones, automobiles and general consumer items. The bright spot is that inventory levels are very low and there are some signs that forward visibility is improving. Scalise said he was encouraged that the Economic Recovery Act recently signed by President Obama would help drive demand for chips in markets such as energy, health care, and infrastructure improvements.
