Toshiba Corp. said on Friday it would buy certain chip-related patents from Micron Technology Inc. and secure licences for all the patents held by Micron unit Lexar Media Inc. for $288 million, ending lawsuits between the Japanese electronics maker and Lexar.

Micron in June acquired Lexar Media, which has been in a legal tussle with Toshiba since 2002 regarding flash memory patent infringement.

Behind Samsung Electronics Co. Ltd. , Toshiba is the world's second-largest maker of NAND-type flash memory chips, widely used in digital cameras, photo-snapping phones and portable music players such as Apple Computer Inc.'s iPod.

Prior to the announcement, shares in Toshiba closed down 1.1 percent at 792 yen, underperforming the Tokyo stock market's electrical machinery index, which sipped 0.4 percent.
