Elpida Memory (Elpida), Japan's leading global supplier of Dynamic Random Access Memory (DRAM), today announced that it has begun mass production of the industry's highest density 2-gigabit Mobile RAM using 50 nm process technology at its Hiroshima fab.
Mobile RAM is an ultra low-power memory that is ideal for use in mobile phones and other portable devices and requires extremely advanced technology for development and production. As a leading supplier of mobile DRAM, Elpida has managed to quickly establish a full-scale 50 nm Mobile RAM production system using ArF immersion lithography and copper interconnect technology.

2-gigabit Mobile RAM uses an x32-bit I/O configuration based on double-data rate (DDR) that can operate at an extremely fast speed of 400 Mbps (200 MHz) to transmit data at the rate of 1.6 gigabytes per second. Thus it can meet demand for high-resolution high-quality graphics display and high bandwidth video play. Moreover, by using advanced 50 nm process technology Elpida has achieved an ultra-small high-density low-power chip that can enhance system performance, increase mobile phone standby time and deliver other functional advantages.

Through its application of advanced process design methods Elpida continues to provide world-class memory products.
