During October elpida company reported about the development of DDR3 SDRAM memory chips with 2 Gbit density, designed for release according to 40 nm standards, and promised to begin the mass production before the end of the present year.
Mass production of 40- nm chips DDR3 SDRAM memory with the density 2 Gbit with the lowered energy consumption began at elpida factory in Hiroshima.
According to available data, the passage in the production of DDR3 SDRAM memory chips with 2 Gbit density from the 50 nm standards to the 40 nm allows to increase output from one plate by 44%. In this case 100% of obtained chips are operational with the speed 1,6 Gbit/s : the maximum standardized DDR3 speed . The memory chips elpida DDR3 SDRAM 2 Gbit, produced according to 40 nm standards, are designed both for the standard supply voltage DDR3 SDRAM, equal to 1,5v, and for lowered 1,35 and even 1,2 v. this positively affects their energy consumption.
In the second quarter next year elpida is intended to master the release of new product in Taiwan daughterly enterprise rexchip in order to reduce the prime production cost . Depending on conditions on DRAM market , Elpida also will be able to transfer 40- nm technical process to the factories of its partners : proMOS and Winbond, in order to additionally increase the release volumes.
