Hynix Semiconductor and ProMOS Technologies today announced the signing of the Amendment to strengthen their existing strategic alliance. According to the Amendment, Hynix licenses to ProMOS 50 nanometer-class DRAM stack process technology, while ProMOS offers to Hynix such DRAM products from its 300mm fab capacity. To achieve timely technology transfer, Hynix plans to commence the government filing process immediately. Additionally, Hynix plans to cooperate with some financial investors to buy 8%-10% portion of shares in ProMOS through private placement to strengthen their long-term cooperation relationship.
