Computer RAM

RAM is the short form of random access memory. It assumes the form of integrated circuits enabling the data to be accessible in any random order. The integrated circuits are mostly integrated into plug-in modules. They are also known commonly as volatile memory since the data stored on them is lost after the power button is turned off. In another form of memory known as read only memory or ROM, information can be read and accessed randomly. But the information stored the ROM cannot be changed unlike RAM which allows such modification.

The RAM’s speed is calculated in units called nanoseconds (ns). If the value of nanoseconds is lower, the speed of the RAM is said to be higher. In modern times, 50 ns computers are being used instead of the 150 and 180 ns that were used in the previous decade. Experts unanimously agree that to make the computer faster and more efficient, it is extremely important to upgrade it on a regular basis by using the latest RAM modules available… as long as they are compatible with the slot. RAM comes into two broad types. One is static RAM while the other is dynamic RAM.

Both these RAM types are volatile in nature, meaning the data is lost as soon as the system is turned off. In spite of this, there are some basic differences between the two. In static RAM, capacitors are replaced by flip flop switches to enhance both efficiency and speed of the computer. The dynamic RAM however is generally stored in a chip equipped with transistors and capacitors. These small vessel-like capacitors function as storage spaces for saving temporary memory. In comparison to the dynamic RAM, the static RAM is priced higher.

This is mainly because the static RAM is equipped to store more information when compared to the storage capacity of the dynamic RAM. As a result of this, sales of dynamic RAM are significantly higher than those of the static RAM. In recent times, new versions of the dynamic RAM have gained prominence among computer buyers across the world. Some of the latest versions of the dynamic RAM that are being used in majority of the servers include ECC (error correcting code), SDRAM (synchronous dynamic RAM), FPM (fast page mode) and EDO (extended data output).

Of these, the EDO RAM is being designed to read the data much faster and enhance the time synchronization between the RAM and the central processing unit. Realising the demand for saving data when the power goes off has prompted a number of companies to design and develop new kinds of non-volatile RAM. Notably, the solid state drives having storage capacities over 642 gigabytes have been made available since 2006. These drives are high on performance and are a preferred choice among computer users these days. Other products reliant on the flash memory are also being developed to prevent data loss
