copied from another thread... DDR isn't even at a sampling stage yet? AMI2 looks to set DDR SDRAM pin spec By Jack Robertson Electronic Buyers' News (05/05/99, 06:03:21 PM EDT) BRISBANE, Calif. — In its first major initiative, the new Advanced Memory International Inc. (AMI2) consortium will standardize the number of pins for the first Double-Data-Rate SDRAM package, slated to come on the market this fall, a member company said. James Sogas, director of the DRAM business unit for Hitachi America Semiconductors (Brisbane, Calif.), said the pin-out specification is one of the last remaining issues to be settled before a standard DDR part can be released. "This is one of the first tasks of AMI2 as part of its long-range program — to assure OEM customers, module makers, connector suppliers and DRAM producers they will have a single unified memory architecture," he said. The DDR SDRAM needs slightly more pins than the 168-pin single-data-rate SDRAM to accommodate higher speed and clocking functions. Sogas said AMI2 members are deliberating over several pin-out configurations, from 184 to 210 pins. The form factor of the DDR package will be the same as for a single-data-rate device, but module and connector vendors will need to deal with the additional number of pins, he said. Sogas said he believes the DDR pin configuration will be standardized "soon" — perhaps within a month. At that point he expects DRAM producers and the chip infrastructure will move quickly to have final sample products ready to deliver. An early DDR introduction is critical in the memory's looming market fight with Direct Rambus DRAM, Sogas said. Intel Corp., a supporter of Direct RDRAM, said the first production chips of that memory are expected to be available by the end of the third quarter.
