Elpida Memory's bankruptcy filing reflects the fact that companies must diversify to cope with trends in the evolution of customer behavior and usage. The DRAM memory industry currently is encountering a shrinking market for traditional PCs, which have been are main DRAM consumer. The rising adoption of mobile computing devices such as tablets does provide an opportunity for DRAM makers, but such devices consume a lot fewer chips than desktops encouraging some chip suppliers to diversify their businesses. Even for memory firms that offer both DRAM and NAND flash and have shifted their expansion focus to the latter product line, a substantial fall in DRAM demand and prices has prompted them to consider new directions to maintain their scale. SK Hynix (formerly Hynix Semiconductor), for instance, has revealed plans to diversify into the foundry business. In fact, entering the foundry business is not new for DRAM makers, especially for second-tier players.
