SEOUL, Feb 7 (Reuters) - South Korean chipmaker SK Hynix Inc said on Tuesday it submitted a non-binding bid last week for a stake in Toshiba Corp's memory chip business, as the firm seeks to boost its NAND flash chip competitiveness.
SK Hynix, in a regulatory filing, said it has not decided on whether to submit a final bid and did not offer details including how big a stake it seeks. The Japanese firm, the world's No. 2 NAND chipmaker, seeks to sell a minority stake of less than 20 percent in the memory business. (Reporting by Se Young Lee)
