Memory
Module is one such integral part of our computer that specifies the
speed and performance of our computer. Computers can easily be
upgraded by adding more RAM or by replacing the one already existing
in the system with the advance version of RAM. One thing that needs
consideration is the type of RAM with the computer configuration. In
other words the new RAM should be compatible with the motherboard of
the system.
Today,
with advancement we all look for purchasing the latest versions of
computer and its parts available in the market. However, it is not
very practical to purchase new version all the times. If you are a
regular user of computer, eventually, you realize that one part or
the other seem to be outdated in your system. The better option is to
replace the parts and upgrade your system. Memory RAM is one such
computer part which is easily available and can be used for upgrading
without affecting other components of the system.
DRAM
(Dynamic Random Access Memory) is the most known type of memory
module for computers today. Initially when we were using SRAM (Static
Random Access Memory) in the computers, there was no requirement of
refreshing the system regularly as it was operating on the principle
of moving current.
In
the early stage of SDRAM (Synchronous Dynamic RAM) era, SDRAM was
considered to be a pioneer in advancement of RAM. It was much faster
and helped in increasing the performance of the computer. Since,
clock speed is the important aspect of the microprocessor to increase
the efficiency of the computer, every RAM manufacturer synchronized
the RAM type with the clock speed. To evaluate the speed of the bus
and the speed of the RAM chip, the clock speed is measured in MHz.
Since,
DDR has better speed, clock speed and better efficiency, it is more
expensive than SDRAM memory and worked at a better memory clock speed
of upto 200Mhz. Soon DDR RAM was superseded by a new RAM – DDR2
RAM, a further advancement in this field. DDR2 performs on the
phenomenon
of ‘Double
Data Rate’ – which means more speed.
DDR3
is the latest version of RAM in the market today which has boomed the
market that works with ‘Triple Data Rate’ system. It is much
faster due to the doubling of the data bus speed and also consumes
less amount of power supply. Today, various sizes of computer RAMs
are available in the market which are ranging from 512MB to 16GB
modules.
