All what you need to know about RAM (Random Access Memory)

Who do not know what is RAM or random access memory, which has become a requirement of devices such as phones, computers and gaming devices, the memory responsible for the reduction of applications that are running. Random memory has several types ,we deny the following:

(Synchronous dynamic random access memory (DAT).) SD-RAM or SDR-RA type I

This type of memory is slow after the thing compared to other pyramids, and consumes a lot of energy, and can not reduce the data in the event of power outage, and is still more cheaply used for its cheap price, it needs to refresh from time to time because it transfers one bit at The speed of the spring is back and the spring is lifted and the process continues. Its speed varies. In the 1990s, the speed was about 66 MHz, and with the continuous development, it reached a maximum speed of 133 MHz.

(Dynamic random access memory and DAT transitive transfer). DD-SDRAM The second type

This type of performance is twice the performance of the first type, due to the rapid development of the field of processors, which doubles DDR forcing manufacturers to create a new technology to double the speed of random memory,

The rate of readability of any speed (RAM) until the maximum speed (333) MHz, but that is not enough for a link to a speed of up to (1333) Mhz. Keep pace with evolution, the technology was developed to DDR2


My dad used the PlayStation 3 and many high-end graphics cards ...  And do not forget DDR3 has a capacity from 512 MB, 1 GB, 2 GB, 4 GB etc ...

The third  type follows dynamic lines of random access memory.

This is the fastest type with its high speed . Its primary function is to transfer data between the processor and the memory. It reduces the size of the front bus from 32 to 16 bytes. It is distributed parallel lines, giving us high speeds of up to 800 MHz. Pathological results of the first and second genotypes.


Even though you have RAM, there are several problems such as motherboard failure with random memory.

The following picture shows the difference between the types of memory in the notebook in the motherboard.


For the form of random memory, they consist of relatively small segments, and carrying and installation is very difficult so installed on special panels easy to carry and installed by professionals.
