Difference between RDRAM and SDRAM

In today’s blog post, we’ll be discussing the difference between RDRAM and SDRAM. Both of these types of RAM are popular options in modern day computers, but what exactly makes them different? And which one is right for you? Read on to find out!

What is RDRAM ?

RDRAM is a type of random access memory that is used in computers. It is a newer type of memory that offers several advantages over older types of memory, such as DRAM. RDRAM is able to achieve higher data transfer rates than DRAM, making it ideal for use in applications where speed is important. RDRAM is also more resistant to changes in temperature and humidity, making it more reliable. However, RDRAM is more expensive than DRAM, so it is not yet widely used.

What is SDRAM?

SDRAM is a type of random access memory (RAM) that is used in computers. SDRAM stands for synchronous dynamic random access memory. It is a type of dynamic RAM (DRAM) that is synchronized with the system clock. SDRAM is faster than DRAM and is used for main memory in computers. SDRAM uses a synchronous interface, which allows it to be synchronized with the system clock. SDRAM also supports burst mode, which allows it to transfer multiple words of data per clock cycle. SDRAM devices are available in various sizes, including 16Mb, 64Mb, and 128Mb. SDRAM is used in PCs, laptops, and servers.

Difference between RDRAM and SDRAM

RDRAM, or Rambus DRAM, is a type of DRAM (dynamic random access memory) that was developed by Rambus Inc. RDRAM operates at much higher speeds than traditional SDRAM, making it ideal for use in high-performance devices such as computers and gaming consoles. RDRAM is also more expensive than SDRAM, making it less popular for general use. SDRAM, or synchronous DRAM, is the most common type of DRAM. It is used in a wide range of devices, from personal computers to servers. SDRAM operates at lower speeds than RDRAM but is much cheaper, making it the preferred choice for most applications.


While both RDRAM and SDRAM are types of computer memory, they have some significant differences. The most obvious difference between the two is that SDRAM uses a single data bus while RDRAM has dual data buses. This means that SDRAM can only send or receive information on one channel at a time, while RDRAM can do so simultaneously on two channels. This makes RDRAM faster than SDRAM. Another difference is that SDRAM typically comes in DIMMs that are 72 pins wide, while RDRAM comes in either 144-pin SO-DIMMs or 168-pin DIMMs.
