Elpida Memory ha annunciato lo sviluppo di chip di RAM DDR per l'ambito mobile caratterizzati da una densità di 2Gb e da un processo di fabbricazione a 40nm. L'incremento del livello di integrazione, rispetto a quello applicato per le sue attuali soluzioni DDR mobile prodotte in tecnologia a 50nm a aventi una densità di 1Gb, ha permesso di raddoppiare la capacità di memorizzazione, a parità di dimensioni fisiche dei chip.
Sempre in virtù del livello di integrazione più spinto, Elpida è riuscita nell'intento di ridurre a meno della metà la potenza elettica dissipata dai nuovi IC (il termine di paragone è rappresentato anche in questo caso dalle soluzioni da 1GB @ 50nm).
Il target della nuova RAM è costituito dalle device portatili di dimensioni contenute, come i telefoni cellulari, gli smartphone e i tablet. I primi sample saranno pronti a giugno mentre la produzione di massa avrà sede a Hiroshima e comincerà a Luglio.
Elpida Memory, 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. In recognition of this need, 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 unique design methods. The newly developed Mobile RAM is Elpida's latest eco-friendly DRAM contribution in support of today's advanced mobile device functionality.
Customers who have used Elpida's 50nm process 1-gigabit products can now expect to find that the new 40nm process 2-gigabit product offers double the amount of memory density without any change in the space needed for chip mounting. Also, the new 2-gigabit product uses less than half the power needed for two 1-gigabit chips.
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.
