TOKYO (Reuters) - Toshiba Corp <6502.T> said on Friday it is looking to sell a majority stake in its prized flash memory chip business to plug a hole in its finances from a $6.3 billion writedown of its U.S. nuclear unit.


The beleaguered conglomerate is "aiming to make a final decision in early fiscal 2017," which starts in April, it said in a regulatory filing.


Toshiba will outline terms of the sale by the end of February, conduct a first round of bids in March and aim to have chosen a preferred bidder or bidders by the end of May, a person with knowledge of the matter told Reuters earlier this week.


A separate source said Toshiba wants to raise at least 1 trillion yen ($8.8 billion) to create a buffer for any fresh financial problems, with interest already received from investment funds, other chipmakers and client companies.
