 02.05.2011   Elpida realizza chip di RAM DDR3 SDRAM da 2-gigabit a 25nm
 

Con il comunicato stampa di seguito allegato, Elpida Memory ha annunciato il completamento della fase di sviluppo di un processo a 25nm finalizzato alla produzione di chip di RAM DDR3 SDRAM da 2-gigabit.

Considerando l'elevatissimo livello di integrazione raggiunto, Elpida Memory può vantare la realizzazione dei chip di SDRAM da 2-gigabit più piccoli al mondo: rispetto alle soluzioni realizzate con la tecnologia a 30nm dal medesimo produttore, i nuovi chip, infatti, sono caratterizzati da una superfice ridotta del 30%.

Nello stesso tempo, però, il consumo di potenza, o meglio il valore dell'intensità di corrente richiesta per la polarizzazione dei dispositivi, risulta ridotto del 20% in condizioni di stand-by e del 15% nel caso di operatività a regime.

I nuovi chip prevedono una tensione di polarizzazione pari a 1.5V o a 1.35V ed offrono prestazioni elevate, tali da renderli conformi con le specifiche della memoria DDR3L-1600 (1600Mbps). Assicurano transfer rate anche superiori alla soglia di 1866Mbps mentre l'avvio della produzione in volumi avverrà a luglio.

Elpida Memory, Inc. (TOKYO: 6665), Japan's leading global supplier of Dynamic Random Access Memory (DRAM), today announced it had developed a 2-gigabit DDR3 SDRAM using an industry-leading 25nm process for memory manufacturing. Using the most advanced process technology available Elpida has achieved the industry's smallest chip size for a 2-gigabit SDRAM.

The newly developed 25nm DRAM process technology requires 30% less cell area per bit compared with Elpida's 30nm process. The chip output for a 2-gigabit DDR3 SDRAM wafer using the new process is about 30% higher versus 30nm.

The new SDRAM is an eco-friendly as it contributes to lower energy consumption by PCs and digital consumer electronics. It outperforms Elpida's 30nm process products by saving on electric current (15% less operating current and 20% less current when on standby).

At the time the 25nm process was developed the structural changes required to shift from a 30nm process were minimized to hold down the capital expenditure needed for ramping up 25nm volume manufacturing.

By the end of 2011 Elpida also plans to begin volume production of 4-gigabit DDR3 SDRAM products using the 25nm process. Compared with the 30nm process a 44% increase in chip output per wafer is expected for this 4-gigabit DDR3 product. In addition, the new 25nm process will be used to support further development of Mobile RAMTM, Elpida's mainstay memory product.

The 25nm process 2-gigabit DDR3 SDRAM can support ultra-fast performance above DDR3-1866 (1866Mbps) and is compliant with low-voltage 1.35V high-speed DDR3L-1600 (1600Mbps).

Both sample shipments of the new 25nm 2-gigabit DDR3 SDRAM and volume production are expected to begin in July 2011.

Elpida continues to be a technology leader in the DRAM industry. It uses innovative design and process technology for the production of high-speed, low-power consumption and low-cost DRAMs.
