South Korea\'s Hynix Semiconductor and Japanese electronics giant Toshiba said Wednesday they have agreed to jointly develop a next-generation memory device. The companies said in a statement that the tie-up to develop spin-transfer torque magnetoresistance random access memory (STT-MRAM) technology -- for use in devices such as smartphones -- would help them minimise risk. Toshiba recognises MRAM as an important next-generation memory technology that could sustain future growth in its semiconductor business, the statement said. The two companies intend to set up a joint production venture once the technology has been successfully developed, it said. Hynix CEO Kwon Oh-Chul described MRAM as \"a perfect fit\" for growing consumer demand for more sophisticated smartphones. \"MRAM is a rare gem full of exciting properties, like ultra high-speed, low-power consumption, and high capacity, and it will play the role of key factor in driving advances in memories,\" he said. The two companies said they have also extended a patent cross-licensing and product supply agreements reached in 2007.
