Elpida Memory, Inc., Japan's leading global supplier of Dynamic Random Access Memory (DRAM), today announced that it had developed a 2-gigabit DDR Mobile RAM using a 40nm process.
The new Mobile RAM has a chip size of less than 50mm2,
which is the smallest chip using 40nm-generation advanced
DRAM process technology at the mass production stage.
In the market for DRAM used in handheld mobile devices, the
need for DRAM products that can conserve greater amounts of
space and power is unrelenting given the ongoing evolution
of small and lightweight mobile phones, smartphones,
tablets and other handheld devices. Elpida has
commercialized 2-gigabit DDR Mobile RAM that is the
smallest 40nm process chip in the DRAM industry and
features lower power consumption through optimizing circuit
and layout design and use of its own design methods. The
newly developed Mobile RAM is Elpida's latest eco-friendly
DRAM contribution in support of today's advanced mobile
The new 2-gigabit product uses less than half the power
needed for two 1-gigabit chips, Elpida said.
At present, demand for 2-gigabit DRAM for smartphones and
other mobile devices is rapidly growing. With its new
Mobile RAM, Elpida plans to meet customer need by ramping
up production as fast as possible to high-volume levels.
Sample shipments are expected to begin in June 2010 with
mass production likely to start in July. Elpida's Hiroshima
Plant is scheduled to handle all production.
