Japan's Elpida Memory Inc. asked a bankruptcy court yesterday to enforce its reorganization plan sale to Micron Technologies Inc., a final step to creating the world's second-largest maker of memory chips, Reuters reported yesterday. Boise, Idaho-based Micron has been losing money as the market for personal computers steadily loses ground to smartphones and tablets. Acquiring Elpida will allow Micron to create greater economies of scale and will rank the company behind Samsung Electronics in the memory chip market. The majority of Elpida's secured and unsecured creditors approved the plan, which included the sale of assets to Micron for 60 billion yen ($582 million) in cash and another 140 billion yen ($1.36 billion) paid in annual installments until 2019.
