A senior Toshiba Corp. executive said the company may invest in chip-maker Elpida Memory Inc., which filed for bankruptcy protection in February.

Toshiba may make a decision as early as Friday about a nonbinding bid to invest in Elpida on its own or as part of a group, according to the executive, who declined to be identified because the discussions are private.

Toshiba isn't interested in all of the firm's assets, the executive said, adding Elpida plans to choose a corporate sponsor for its revival plan in May.
