SDRAM and DDR RAM are memory integrated circuits used in computers. The difference between the two is the speed because SDRAM is a single data rate which is slower than DDR RAM that stands for the double data rate. Which means the chip reads or writes two words of data per clock cycle.

∙ 14y agoRDRAM (Rambus dynamic random access memory) and SDRAM (synchronous dynamic random access memory) are two different types of memory technology. RDRAM is newer and in some cases faster, but SDRAM is less expensive.
The most important thing to know is that you cannot use RDRAM in a system designed for SDRAM or vice versa. The two types of modules are different sizes and shapes, so they won't even fit into the same memory slots. You should buy whichever memory type was designed for your system. Answer: RDRAM stands for Rambus Dynamic Random Access Memory. SDRAM stands for Synchronous Dynamic Random Access Memory. The two memories are completely different memory technologies and are not compatible with each other. RDRAM is a unique design developed by a company called Rambus, Inc. RDRAM is extremely fast and uses a narrow, high-bandwidth "channel" to transmit data at speeds much faster than SDRAM.

This means data throughput on DDR memory is twice as fast, hence the name "Double Data Rate". Also, they are physically different: A DDR modules has one notch on the contact strip, SD modules have two. i donot know SDRAM comes in 100MHz and in 133MHz where as DDR comes in 266MHz, so DDR has double speed as comapred to SDRAM. SDRAM has 2 notches and DDR has only 1 notch.*and it is small in size

∙ 15y ago== == DDR stands for "Double Data Rate." This means that each time your computer gets data, it gets it on the upcycle of the clock as well as the downcycle of the clock. So it is catching double the data than before -- which means it can process twice as fast. SDRAM stands for "Synchronous Ram." The RAM is synchronized with the clock cycle and grabs a chunk of data each clock cycle so it is synchronous. Notice that it does not grab two chunks as does the DDR. So the DDR is twice as fast.

Does rdram have to be replaced with rdram or can it be replaced with sdram if all chips are replaced?
no
What is the difference between a sdram and a mobile sdram?
Physical size of the memory card. Mobile sdram is smaller than sdram for desktops.
What is the difference between shared dual channel ddr2 SDRAM at 533mhz or ddr2 SDRAM at 667mhz?
Obviously the difference is speed.
Can you explain the difference between Dram and SDram?
Dram and Sdram are two different types of memory.
How do you change from one type of RAM to another?
Please give more info.. SDRAM to RDRAM? slower to faster?
The main difference between sdram and dram is that dram is?
The main difference between Synchronous random access memory, SDRAM and Dynamic Random Access Memory, DRAM is that SDRAM is synchronous while DRAM is asynchronous. As such, SDRAM is efficient in retrieving and storing data than DRAM.
What is the difference between SDRAM and DDRAM?
http://en.wikipedia.org/wiki/DDRAM http://en.wikipedia.org/wiki/SDRAM It explains everything.
What is drdram?
Direct Rambus DRAM or DRDRAM (sometimes just called Rambus DRAM or RDRAM) is a type of synchronous dynamic RAM. RDRAM was developed by Rambus inc., in the mid-1990s as a replacement for then-prevalent DIMM SDRAM memory architecture.
What is rdr and ddr ram?
Rambus Dynamic Random Access Memory (RDRAM) is a memory subsystem that promises to transfer up to 1.6 billion bytes per second. It is a type of synchronous dynamic RAM. RDRAM was developed in the mid-1990s as a replacement for then-prevalent DIMM SDRAM memory architecture. RDRAM was going to become the market standard but then DDR RAM came to scene. DDR SDRAM (double data rate SDRAM) is synchronous dynamic RAM (SDRAM) that can theoretically improve memory clock speed to at least 200 MHz. It activates output on both the rising and falling edge of the system clock rather than on just the rising edge, potentially doubling output. It's expected that a number of Socket 7 chipset makers will support this form of SDRAM.
List 5 types of memories of a computer?
Five types of computer memory are: Dynamic Random Access Memory (DRAM) Synchronous DRAM (SDRAM) Static RAM (SRAM) Double Data Rate RAM (DDR) Rambus DRAM (RDRAM)
Is there a functional difference between DRAM and SDRAM memory, and if so, which is best for the price?
It's the same thing, Synchronous Dynamic RAM (SDRAM) is typically just a different name for DRAM.
What is the difference between DDR2 SDRAM PC2 133 168pin and DDR2 memory?
speed?maybe.but more likely the spelling.."DDR2" has no"SDRAM PC2 133 168pin" unlike the"DDR2 SDRAM PC2 133 168pin"It's really hard to see it at a first glance..
