1999: Rambus DRAM (RDRAM) - Computer Memory
RDRAM or DRDRAM (Direct Rambus DRAM) is a type of synchronous dynamic RAM and is the most famous example of a failed attempt to replace SDRAM. It was developed in the late 1990s by Rambus and was intended to launch in concert with Intel's Pentium 4 processor. Intel threw its weight behind the technology and invested $300 million in Samsung's production capacity to support the launch of the Pentium 4 in 2000. The main advantage of rambus memory was greater bandwidth than SDRAM and the surfacing DDR SDRAM. Intel canceled the effort and limited Rambus support to a few server and workstation-targeted platforms due to industry opposition. Rambus memory was expensive to produce in part caused by high licensing fees.Rambus exhibited hostile behavior when it sued its potential customers over IP infringements in the SDRAM and DDR space. The use of Rambus memory was later briefly discussed for graphic cards, but remained limited to some server, and networking devices, as well as core memory technology in Sony's PS3 game console.
