清华紫光竞购闪存巨头美光

China's Tsinghua Unigroup has offered to buy U.S. memory chipmaker Micron Technology for US$ 23 billion. That's according to a report in the Wall Street.

The report says Tsinghua's offer stands at US$ 21 per share for Micron. That's a 19.3-percent premium on the stock's closing price Monday.

The proposed purchase by the state-backed private equity firm would be the largest-ever Chinese takeover of an American company if the deal goes through.
