Rambus DRAM (RDRAM'), and its successors Concurrent Rambus DRAM (CRDRAM) and Direct Rambus DRAM (DRDRAM), are types of synchronous dynamic RAM developed by Rambus from the late-1980s through to the early-2000s.The third-generation of Rambus DRAM, DRDRAM was replaced by XDR DRAM. such changes may, at rambus inc.’s discretion, be incorporated in new versions of the software. Samsung Electronics has changed that by completing development of a much more affordable Rambus DRAM. Rambus DRAM (RDRAM), and its successors Concurrent Rambus DRAM (CRDRAM) and Direct Rambus DRAM (DRDRAM), are types of synchronous dynamic random-access memory (SDRAM) developed by Rambus from the 1990s through to the early-2000s. It transfers data at speeds up to 800MHz over a narrow 16-bit bus called a Direct Rambus Channel. bandwidth of Direct Rambus DRAMs; and the order-sensitive performance of modern DRAMs — motivated our investigation of a hardware streaming mechanism that dynamically reorders memory accesses in a Rambus-based memory system. RDRAM is used mainly for video accelerators, and also in the Ultra 64 from Nintendo. It utilizes Rambus DRAM (RDRAM) memory platform. 03. MAXTOR (HDD manufacture and supply) IPO on NASDAQ. Typical SDRAM can transfer data at speeds up to 133 MHz, while standard RDRAM can crank it up over 1 GHz. RLDRAM. Experimental. In the early '90s, Intel was a major DRAM buyer and resold the chips in motherboards and PCs assembled for OEMs. DDR and Direct Rambus memory are not interchangeable, and users still have to pay more for Direct Rambus memory, although the premiums are dropping as DRAM companies ramp up volume.
