Hynix 1Gb 54nm Mobile RAM
Hynix today revealed that it has produced the first 1-gigabit (256MB) mobile DDR2 memory based on a 54 nanometer manufacturing process. Shrinking the chip design has let the company simultaneously raise its maximum clock speed up to 1,066MHz -- the same as desktop memory -- but also to drastically reduce the power versus earlier mobile RAM. The denser memory consumes about half as much power as earlier mobile DDR2 and just 30 percent that of full-fledged desktop memory.
The firm pitches the technology as particularly useful for high-end smartphones but also for those mobile Internet devices and netbooks that need a high amount of bandwidth (up to 8.5GB per second with dual memory channels) but still need to keep energy use in check.
Hynix doesn't name its clients but does say it expects to start shipping memory in the second half of the year.
