Shares in SK Hynix were up 1.5 percent, while those of domestic peer Samsung Electronics Co Ltd - which announced a new smartphone late on Wednesday - were almost flat. SK Hynix was a member of a consortium led by US private equity firm Bain Capital which bought the majority of Toshiba Corp's memory chip business last year. On Wednesday, people familiar with the matter told Reuters Bain had chosen banks to manage an initial public offering of Toshiba Memory as early as September.
