Description While you'd likely get chips at a Mexican-Greek restaurant called El Pita, they wouldn't improve your memory like chips from Elpida. The company, originally formed as a 50-50 joint venture of Japanese electronics giants Hitachi and NEC, is a maker of DRAM devices. The last big DRAM supplier in Japan, it competes with memory device kingpin Samsung Electronics and leading contenders Micron and Hynix. Elpida offers advanced memory technologies, such as double data rate (DDR) DRAMs and Rambus-based DRAMs, as well as memory modules, for a wide variety of electronic equipment. The company gets about three-quarters of sales from the Asia/Pacific region. In 2012 Elpida filed for bankruptcy protection in Japan.
