6/27/2001: The first official specifications of the DDR-II
A whole of 120 companies has approved recently in a meeting of the JEDEC in Tokyo the first specifications of the future memory DDR-SDRAM-II. Since it was of waiting, the new review gives priority to the increase of the speed as well as to the reduction of the consumption (one of the foibles of the memory current SDRAM, which works to 3,3 V), making use of the proper relatively low latency of this architecture (very much minor that in the RDRAM of Rambus).
The current memory DDR-SDRAM works to 2,5 V (one codes still something raised for portable) and uses for the most part an interface DIMM of 184 pines. The DDR-II limits the consumption to 1,8 V and almost safely it will be incompatible with the current badges, between other motives for using a physical interface of 232 pines (in basic badges for office PCs).
Two have been the speeds approved for the DDR-II: on the one hand, the modules PC3200, which work to 400 MHz and with a band of 3,2 GB/s; for other the modules PC4300, to 533 MHz and with a breadth of 4,3 GB / century
One hopes that for 2002 the first memory modules should be available, and between 9 and 18 months later, already in 2003, it would begin his commercialization on the final market.
If this was not small, also one begins hearing to speak about the DDR-III, which apparently will be provided with the support of Intel (principal guardian of the RDRAM) and will have with technology of the future memory DRAM Advanced. But good, this is another history...
