Samsung Electronics announced that it has developed the world's first 50nm DDR2 dynamic random access memory chip (DRAM). According to Samsung, the chips use a new three-dimensional transistor design which helps the chip retain memory better and increases production yields by 55 percent.
Samsung is the world's top memory producer with about 30 percent of the market. The company believes the 50nm process can be adapted to other chips including graphics and mobile DRAM. Mass production is expected in 2008.
