As expected, Toshiba Corp. agreed to sign a memorandum of understanding (MOU) acquire NAND flash manufacturing capacities from its joint ventures (JVs) with SanDisk Corp. Even though Toshiba did not buy all the stakes in Flash Partners and Flash Alliance from its partner, the take over of 30% of JVs means that Toshiba now controls about 65% of the manufacturing companies.


Toshiba and SanDisk have signed a non-binding MOU on the reallocation of wafer output and equipment ownership and funding at their two joint ventures producing NAND flash memory on 300mm wafers at Toshiba’s Yokkaichi Operations in Japan, in response to a proposal from SanDisk.

The move is designed to enhance the production flexibility of NAND flash memory in line with the rapidly changing marketplace and to optimize each company’s business strategies, said the companies. The details will be set forth in definitive agreements.

Fab 3 and Fab 4 at Toshiba’s Yokkaichi Operations are currently operated by Flash Partners and Flash Alliance, the production joint ventures between Toshiba and SanDisk. Investment in the manufacturing equipment installed at the two fabs is equally shared by Toshiba and SanDisk through the JVs, with the same capacity allocated to each company. The revised allocation will make Toshiba the sole owner of some 30% of the total capacity. The remaining about 70% will still be owned by the JVs, and the production capacity allocated to the JVs will be divided equally between Toshiba and SanDisk. As a result, Toshiba’s overall allocation of capacity in the two fabs will increase by about 30% to approximately 65%. By expanding its production capacity efficiently, Toshiba aims to increase sales of NAND flash memories.

Toshiba believes that the NAND flash memory market will continue to grow in the medium to long term with average annual bit growth rate of more than 200%, supported by such established applications as cellular phones and digital camcorders, and by emerging applications such as solid state drives (SSDs) for notebook computers and servers. SanDisk, however, will get rid of certain assets which value is on the decline due to very low prices of NAND flash.

Sole ownership of some 30% of the total capacity of the two fabs will allow Toshiba to be more flexible in making decisions on production volumes in line with changes in market demand, according to the company. Acquisition of part of the existing production equipment in use will also allow Toshiba to quickly expand its manufacturing capabilities at a lower cost and with a shorter ramp-up time than by procuring new equipment.
