Random Access Memory is a key component of the makeup of your PC, laptop or server. It acts like a fetcher and receiver that processes at random, new and old information and can release that information at will to take on new intellect. RAM is where your operating system, applications and current state is kept for fast accessing.

Each time your computer is turned off your RAM is wiped clean and on restart collects data from your operating system and files and reloaded.  Other storage devices like hard drives and optical devices are much slower than RAM.

RAM comes in two primary types: Dynamic Random Access Memory and Static Random Access Memory.

DRAM And SRAM Memory

Dynamic Random Access Memory needs to be powered constantly to ensure data is stored.  Static Random Access Memory does not require constant power and does not need to be periodically refreshed and is mainly used in personal computers and because of its smaller sized used in application’s CPU cache memory and hard drive buffers. SRAM is also used in electronics like children’s toys.


Double Data Rate Synchronous Dynamic Random Access Memory superseded DDR RAM and is able to provide twice the bandwidth with the same latency as DDR RAM. DDR2 SRAM is twice as fast as the traditional DDR RAM. Superseding DDR2 SRAM as you can guess is DDR3 SDRAM. This makes the online gambling Canada and the rest of the world has to offer even better, as games work at their optimum.


Double Data Rate type three Synchronous Dynamic Random Access Memory is an improvement over DDR2 SDRAM.  DDR3 SDRAM has faster bus speeds and higher peak throughput than traditional DRAM. DDR3 RAM offers chip capacity between 512MB and 8G which enables 16G memory module size.

DDR3 SDRAM has a transfer rate of 0.4 to 1.06 Gigatransfers per second and has lower power consumption by up to 30% compared to DDR2 SDRAM.  It also features better cooling capabilities and much higher bandwidth performance. However, DDR3 SDRAM has usually has higher CAS latency.  DDR3 SDRAM is useful when you need faster data transfer between frame buffers and your graphic cards.


Significantly standing out between DDR3 SDRAM and DDR4 SDRAM is the increased transfer rate; DDR4 SDRAM transfer clocks double and that it can channel bandwidth rate at double of its predecessor DDR3 SDRAM, which is 25.6 GBPS.

DDR5 Memory Is On Its Way

The new future promises the launch of the all-new DDR5 RAM, which promises a faster more robust experience than the current DDR4 SDRAM. Not only will DDR5 RAM produce better power efficiency but also deliver twice the bandwidth density. Because DDR5 RAM is said to be conjoined with a USB Flash drive, high capacity persistent memory should be achievable due to data being stored between reboots.  One of DDR5 RAM’s most significant features is that it is backward compatible with DDR4 RAM.

As the demand for new technology increases and so does the amount of time we spend online, so does the demand for hardware that can accommodate it.  RAM is attempting to bridge the gap between new and old tech for increased performance and memory capability for more efficient technology.
