Activists are demanding a way to hold the memory-chip maker accountable to its promises to protect the environment and embrace communities of color in central New York. Days after Micron broke ground on a $100 billion chip factory in New York state, a coalition of environmentalists, labor unions, and civil rights groups are urging the US tech giant to sign a deal that would make a series of promises to be a good neighbor legally enforceable. Micron's megafab to make memory chips is on track to become the biggest commercial development in state history and the largest chipmaking complex in the country . Officials held a groundbreaking ceremony in the city of Clay, near Syracuse, last Friday. The first chips could arrive in five years, though the entire site won't be finished for 20 years.
