Computer RAM Memory and Different Types
Computer RAM Memory is one of the most common memory units which are extensively used in all of
the desktop computers that you find today. RAM is an acronym for Random Access Memory and it
primarily takes the name from nature of the work. RAM can easily gain access to any of the cells of the
virtual memory unit at any given time for the purpose of storing or retrieving information, provided you
know the precise row and column which intersects at that particular cell. Computer Memory is of
different forms and capacities and every form of memory is used for different purposes. Starting with
SRAM, or the Static Random Access Memory, the memory is primarily used as the computer’s cache
The DRAM or Dynamic Random Access Memory is yet another significant Computer Memory where the
memory cells are paired with the transistor and capacitor that needs constant refreshing activity. The
EDO DRAM or Extended Data out Dynamic Random Access Memory is the memory unit where
processing of information takes place at extremely rapid pace. This typical computer RAM Upgrade
Memory will not wait for the processing until the first bit is completed. The SDRAM or Synchronous
Dynamic Random Access Memory has extremely high processing rate which is about 528 Mbps. The
data is stored as a sequence and fast accessing method is used by this memory.
The personal computer RAM also comes as DDR1 and DDR2, and the top priority ones include 256MB
PC2 4200 DDR2 RAM Memory and 512MB DDR2 PC2 5300 RAM Memory respectively. DDR1 and DDR2
computer RAM Upgrade Memory units are designated as First Generation and Second Generation
devices. DDR 1 has Double Data Rate interface which is designed for two data transfers per differential
clock and have maximum processing speeds of up to 400 MHz. The DDR 2 computer RAM Memory units
on the other hand have the speed level of 400MHz as lowest and it can reach to 532MHz levels.
Irrespective of the fact whether you are buying 256MB PC2 4200 DDR2 RAM Memory or the 512MB
DDR2 PC2 5300 RAM Memory, the issue that continues is that you have to buy form the genuine
electronic store. Do not be in a hurry to buy Computer RAM from any fake store as it would not give you
the advantage of high efficiency.
Besides DDR1 and DDR 2 RAM memory units, ROM or the Read Only Memory is also quite effective and
primarily used for read only purpose. ROM is also known as Firmware and it has integrated circuit
programmed with the data. ROM as explicit memory unit is used in many number of digital computer
devices like Xbox and many other types of video game console box. Make sure you check about the
specification of the gaming console as it would explicitly list ROM specifications.
Get ready to upgrade your computer RAM memory and let the work efficiency increase. Keep in your
mind to do extensive search and comparison before finally making the decision.
