Elpida Memory has developed a 2-gigabit (2Gb) DDR mobile RAM using a 40nm process, according to the company. The new mobile RAM has a chip size of less than 50-square millimeter, which the company claims is the smallest chip using 40nm-generation advanced DRAM process technology at the mass production stage.
Elpida said customers who have used its 50nm 1Gb products can now expect to find that the new 40nm 2Gb product offers double the amount of memory density without any change in the space needed for chip mounting. Also, the new 2Gb chip uses less than half the power needed for two 1Gb chips.
Elpida expects to begin sample shipments of its 40nm-made 2Gb chips in June 2010, with mass production likely to start in July. Its Hiroshima Plant is scheduled to handle all production, according to the company.
