Queries You May Have About Ram: Random Access Memory

What is RAM ?

Alternatively referred to as main memory, primary memory or system memory.Basically RAM (random access memory) is a hardware device that allows information to be stored and retrieved on a computer.It is normally associated with DRAM, a type of memory module.Here information is accessed randomly instead of sequentially like it happens in CD or hard drive.In RAM,data is accessed much faster.Unlike ROM or hard drive,RAM is a volatile memory means if the computer is powered off all data contained is lost surprisingly.

History of RAM

The very first random access memory(RAM) was introduced in 1947 with the use of Williams tube.It was based on the technology of CRT(cathode ray tube) where all the data was stored on the face of CRT as electrically charged spots.With further invention,magnetic-core memory introduced.It became second most widely used RAM.Frederick Viehe is credited for much of his work in this field.

As RAM serves as temporary storage and working space for the operating systems and applications, it can also be used in numerous ways for example virtual memory, RAM disk and shadow RAM.In today’s technology, random-access memory comes in the form of integrated circuits.

Types of RAM

Along with some advancement in RAM technology there have been different variations in it.Some of the more commonly used form of RAM are Static RAM(SRAM) and dynamic RAM(DRAM).Not to be confused with SDRAM. Synchronous dynamic random-access memory(SDRAM) is a kind of dynamic random access memory(DRAM) where the operation is controlled by an externally supplied signal.


DDR SDRAM(often known as DDR1), is a form of semiconductor memory. Unlike previous technologies,SDRAM is designed to synchronize itself with the timing of the CPU. It achieves it’s speed increase by transferring data twice per cycle. Both on the rising and the falling edge of clock signal.


DDR2 SDRAM,very similar to DDR SDRAM is a successor of the later.It can be operated at a higher speed than DDR or DDR1 offering a greater bandwidth potential,operates on less power also generates minimum amount of heat.Typically DDR2 SDRAM clock rates are 200,266,333,400 and 533 KHz    


This is the successor of DDR2 with better advancement in bandwidth.The major benefit of DDR3 SDRAM over it’s predecessor is it’s ability to transfer data twice the rate of DDR2.It comes with higher performance at lower power.For a laptop computer,DDR3 RAM sticks have 204 pins.


This is the abbreviation for ”double data rate fourth generation synchronous dynamic random-access memory”.This is the latest variant of memory in computing. DDR4 can operate with higher speed thanks to it’s increased transfer rates and low power consumption.It operates at a voltage between 1.2v and 1.4v having frequency between 800 and 2133 MHz. DDR4 modules are slightly thicker than DDR3 in order to accommodate more signal layer. Achieving more than 2GBps per pin provides upto 50 percent increased performance and bandwidth.

Thanks for your attention! Give feedback. Stay tuned! keep smiling.
