Despite suggestions that it might be hedging its bets by negotiating for licences to IBM memory chip designs, Motorola Inc has signed a memorandum of understanding with Toshiba Corp for Phase II of their joint technology agreement, which gave the US firm a licence to 4M-bit chips designed by Toshiba and involved the creation of an equally owned fabrication company in Japan. The second phase of the agreeemnt covers memory chips in capacities of 16M-bits and up. Toshiba wants the joint company to make the 68030 too, but Electronic News hears that Motorola is tying that concession to its achieving a minimum volume of sales of other chips in Japan.
