Micron Technology Inc. (MU.N: Quote, Profile , Research) said on Tuesday it has settled a class-action lawsuit that will reduce its previously announced first-quarter profit by up to $80 million.

The lawsuit, which followed a 2002 U.S. Justice Department inquiry into the memory chip industry, covered people and entities that bought a type of computer memory known as DRAM directly from suppliers from April 1999 through June 2002.
