A consortium seeking to buy Toshiba Corp.'s prized memory chip unit may delay closing the deal in order to wait for a court decision on whether the sale should be blocked, sources said Tuesday.

Western Digital Corp., Toshiba's chip production partner, opposes the sale and is seeking a preliminary injunction against it in a California court. The U.S. hearing is scheduled to take place July 14, where a decision could be handed down.

Cash-strapped Toshiba is rushing to sell the unit, Toshiba Memory Corp., to raise funds to eliminate its negative net worth and avoid being delisted from the Tokyo stock market.
