KAWASAKI, Japan , DUESSELDORF , Germany , and SANTA CLARA, Calif., Nov. 19 /PRNewswire/ -- NEC Electronics Corporation and its subsidiaries, NECElectronics America, Inc. and NEC Electronics ( Europe ) GmbH, today introduced two new technologies for the manufacture of 40-nanometer (nm) system-on-chip(SoC) devices with embedded dynamic random access memory (eDRAM). The UX8GDeDRAM technology boasts clock speeds up to 800 megahertz and low operating power, making it optimal for use in consumer electronics products such asdigital video cameras and game consoles. The UX8LD eDRAM technology featureslow leakage-current levels that reduce power consumption by as much two-thirds compared to equivalent SRAM, making it ideal for use in mobile handsets andother portable devices that require low stand by power.
The UX8GD and UX8LD technologies combine leading-edge 40 nm CMOS process technology with NEC Electronics' unique eDRAM process technology, and are available in memory configurations up to 256 megabits. Cell size is 0.06 square micron meters, 50 percent smaller than the company's previous 55 nmUX7LSeD eDRAM. This translates to a 50 percent reduction in overall chip size, which contributes to lower bill-of-materials costs.
The new 40 nm technologies also leverage innovative high-dielectric(high-k) materials -- such as hafnium gate dielectrics, nickel-silicide gate electrodes, and zirconium-oxide DRAM capacitors -- that have been proven inNEC Electronics' 55 nm UX7LSeD technology. These innovations lower the concentration of impurities and parasitic resistance in the channels,resulting in benefits such as lower leakage current between the drain and source, longer-term data storage, fewer variations in transistor performance,and greater performance of both logic and memory.
As consumers demand smaller form factors and longer operating times inmobile applications and other electronic products, semiconductor companies must deliver devices with higher performance, smaller footprints, lower power consumption, and lower costs. To meet these requirements, the development and implementation of advanced process technologies is vital.
The advantages of the new technologies featured in NEC Electronics' 40 nmeDRAM will enable customers to more easily build electronic digital consumer products such as digital video cameras, game consoles, and mobile phones with lower power consumption and smaller and slimmer form factors.
