TOKYO -- The tussle over who will claim ownership of Toshiba's memory chip unit is heating up, as bidders sweeten their offers to the troubled Japanese electronics maker. Cash-rich Apple is being pulled into the fray by rival suitors, as they try to make their offers more appealing.
There are two main competitors for Toshiba Memory. On one side is a consortium led by U.S. investment fund Bain Capital that includes chipmaker SK Hynix of South Korea. On the other is a team led by U.S. chipmaker Western Digital and investment fund Kohlberg Kravis Roberts, also of the U.S.
