Micron agreed to buy Elpida in a deal that would double the U.S. company's share of the global market for dynamic random access memory. The deal would help Micron compete with Samsung Electronics.
Elpida and Micron have not commented on the report.
Last week, Micron agreed to acquire Elpida's equity for 60 billion yen ($753.7 million) and pay creditors a total of 140 billion yen in annual installments until 2019. Micron will also buy a 24 percent stake in Taiwan-based Rexchip Electronics from Powerchip Technology for $334 million.
