What does RDRAM stand for?
From Wikipedia, the free encyclopedia. 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.
What are the key features of Rambus technology?
The key feature of Rambus technology is a fast signaling method used to transfer information between chips. Instead of using signals that have voltage levels of either 0 or Vsupply to represent the logic values, the signals consist of much smaller voltage swings around a reference voltage, Vref.
What is SDRAM and RDRAM?
Rambus Dynamic Random Access Memory (RDRAM) is a memory subsystem designed to transfer data at faster rates. RDAM is made up of a random access memory (RAM), a RAM controller and a bus path that connect RAM to microprocessors and other PC devices.
How do I find my RDRAM?
The speed of your RDRAM is determined by your FSB setting using a multiplier….When you go out to buy RDRAM, you’ll be looking for one of three types that Intel has defined:
- PC800 RDRAM – operating frequency of 400MHz.
- PC700 RDRAM – operating frequency of 356MHz.
- PC600 RDRAM – operating frequency of 300MHz.
What happened to RDRAM?
In 2003, Intel released the 875P chipset, and along with it dual-channel DDR400. With a total bandwidth of 6400 MB/s, it marked the end of RDRAM as a technology with competitive performance. Rambus also developed and licensed its XDR DRAM technology, notably used in the PlayStation 3, and more recently XDR2 DRAM.
Is SDRAM better than RAM?
this can be additionally why the speed of SDRAM and DDR RAM is rated in rate instead of in nanoseconds (ns)….Difference between DDR and SDRAM:
| SDRAM | DDR |
|---|---|
| It refers as synchronous dynamic random access memory | It refers as Double data rate SDRAM |
| SDRAM prefetch timing is 1ns | DDR prefetch timing is 2ns |
What is the difference between SRAM and RDRAM?
RDRAM has memory controllers embedded on each memory chip, while SDRAM uses a single memory controller located on the northbridge of the motherboard. RDRAM modules can only be used in pairs, while SDRAM modules can be used individually. 6. RDRAM modules run with more heat compared to SDRAM modules.
What is EudraCT?
Welcome to the EudraCT public home page EudraCT (European Union Drug Regulating Authorities Clinical Trials Database) is the European database for all interventional clinical trials on medicinal products authorized in the European Union (EEA) and outside the EU/EEA if they are part of a Paediatric Investigation Plan (PIP) from 1 May 2004 onwards.
What is the history of RDRAM in motherboards?
The first PC motherboards with support for RDRAM debuted in late 1999, after two major delays. RDRAM was controversial during its widespread use by Intel for having high licensing fees, high cost, being a proprietary standard, and low performance advantages for the increased cost. RDRAM and DDR SDRAM were involved in a standards war.
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.
However, RDRAM got embroiled in a standards war with an alternative technology— DDR SDRAM —and quickly lost out on grounds of price, and later, performance. By around 2003, DRDRAM was no longer supported by any personal computer.
