 23.12.2009   Elpida: sono i produzione i chip di DDR3 da 2gigabit @ 40nm
 

Con il comunicato stampa di seguito allegato, Elpida Memory ha reso noto di aver avviato la produzione in volumi dei chip di RAM di tipo DDR3 con densità pari a 2 gibabit mediante il processo di fabbricazione a 40nm. Il comunicato del maker segue l'annuncio relativo al completamento dello sviluppo della nuova tecnologia, giunto soltanto pochi mesi fa (lo scorso Ottobre per la precisione, ndr).

In accordo al produttore, il processo di fabbricazione a 40nm consente la realizzazione di un maggiore numero di chip per wafer rispetto alla precedente generazione di DDR3 ottenute con la tecnologia a 50nm (il delta è pari a circa il 44%); le nuove DDR3, inoltre, pur offrendo un bit rate pari a ben 1.6Gbps, consumano meno della versione precedente.

Infatti, i nuovi chip sono polarizzabili con una tensione compresa tra 1.2V e 1.35V, mentre il valore omologo per le DDR3 standard è pari a 1.5V: ne consegue, afferma Elpida, una riduzione del consumo di potenza pari a circa il 50%.



TOKYO, JAPAN, December 22, 2009 – Elpida Memory, Inc. (TOKYO: 6665), Japan's leading global supplier of Dynamic Random Access Memory (DRAM), today announced that its Hiroshima Plant has begun volume production of 40nm process 2-gigabit DDR3 SDRAMs. Since completing development of the DDR3 SDRAM last October it has taken Elpida only two months to ramp up mass production.

The new 2-gigabit DDR3 SDRAM achieves 44% more chips per wafer compared with Elpida's 50nm DDR3 SDRAM and a 100% yield for DDR3 products that operate at 1.6Gbps, the fastest speed standard for current DDR3. It also supports high-speed products. Compared with 50nm products, it uses about two-thirds less current and supports 1.2V/1.35V operation as well as DDR3 standard 1.5V, resulting in reduced power consumption of around 50%.

Initially, Elpida plans a phased expansion of 40nm 2-gigabit DDR3 SDRAM mass production at its Hiroshima Plant. In the second quarter of 2010, 40nm process production will also begin at Rexchip, a subsidiary in Taiwan, to increase the manufacture of 40nm process products in order to lower products costs. Depending on conditions in the DRAM market, Elpida may transfer 40nm process technology to foundry partners ProMOS and Winbond to expand production based on this technology to an even higher level.
