Understanding RAM itself is a computer component that serves as a temporary memory storage when the computer is being used.
RAM storage is temporary, this means that after the computer is dead, the RAM will return empty and filled with new data needed when the computer is used again. Interestingly, the contents of RAM can be accessed randomly or randomly so that RAM is faster than hard disk or other storage media.
RAM itself has a function that is quite vital in computer devices. The main function of RAM is to speed up the processing of data on the computer. No wonder, the bigger the RAM installed, the faster the computer works.
In addition, RAM also serves as a storage medium when the computer or laptop in a state of life. For example, when you type a document in Microsoft Word, then you close it without saving it first, the document you type will be stored in RAM memory. So, you can open the document through the last history of Microsoft Word earlier.
Here are the types of RAM and functions along with the characteristics that you should know.
1. DRAM (Dynamic Random Access Memory)
This type of RAM is a semiconductor memory that requires a capacitor as a pedestal to refresh existing data in it. This RAM has a higher speed than EDO RAM. However, it is lower than SRAM.
DRAM uses one transistor and capacitor per bit in its structure. This makes this RAM has a high enough density. DRAM has a working frequency that varies between 4.7 Mhz to 40 Mhz.
2. SDRAM (Sychronous Dynamic Random Access Memory)
SDRAM into RAM that has a high enough speed compared to other types of RAM that is the speed up to 100 - 133 Mhz. This RAM is widely used in 1996 to 2003 and is a type of RAM that has 168 Pin data transfer channels. The characteristics of this RAM there are two slits in the legs. This RAM will be placed on the DIMM / SDRAM slot on the motherboard that can hold memory from 16 MB to 1GB.
3. RDRAM (Rambus Dynamic Random Access Memory)
This component was introduced in 1995 with a speed of 600 Mbytes / sec. In 1997, the speed of RDRAM increased to 700 MBps, and in 1998 to 1.6 GBps. No wonder, this RAM was originally developed for computers with Pentium 4 processors or for gaming devices. The memory slot for RDRAM is 184 pins.4. SRAM (Static Random Access Memory)
This type of RAM is made of a kind of semi conductor that does not require a capacitor and does not require frequent refreshment so performance can be faster. This is because these components only use transistors without capacitors.
SRAM is designed using a six-transistor cluster design to store every bit of information. Unfortunately, SRAM has the disadvantage that its cost of production is expensive. No wonder, this RAM is only available in small capacity and used for the really important part. This chip is often used for memory chace. SRAM speed is able to offset the speed of 500 MHz processor or more.
5. EDORAM (Extended Data Out Random Access Memory)
RAM was developed in 1995 and has a faster ability to read and transfer data compared to other types of RAM. The memory slot for EDORAM is 72 pins. The shape of this component is longer than the SIMM RAM. No wonder this RAM is very suitable to be installed on all Pentium computers. In addition, this component is also suitable to be installed on a computer with a bus reaching 66 Mhz.
6. FPM DRAM (First Page Mode DRAM)
This type of RAM is the original form or initial form of DRAM. The maximum transfer rate for the L2 cache is approximately 176 MB per second. FPM works in the frequency range 16 MHz to 66 MHz with access time up to 50ns.
7. Flash RAM
Flash RAM is a type of low-capacity memory used in electronic devices such as TVs, VCRs, to old phones. This Momori is installed on devices that require a refresh with little power.
8. VGRAM (Video Graphic Random Access Memory)
VGRAM is typically used to store pixel content for a graphical exposure. Use of this chip will provide good video performance and reduce the pressure on the CPU.9. DDR SDRAM (Double Date Rate SDRAM)
This type of RAM to be one that has a very high speed among the types of RAM. No wonder, this RAM is used in various devices today. This RAM is capable of running two instructions at once in the same time unit. This memory has 184 pins. This type of RAM also consumes less power.
The next types of RAM such as DDR2 RAM to DDR3 RAM is the development of DDR SDRAM. Both types of RAM is used in many computers today because more power saving and more optimal with high speed. For this type of memory capacity was quite large up to 4 GB per chipnya.
10. SO - DIMM (Small Outline Dual in-line Memory Module)
This memory is the type of memory used in notebook devices. Physical form is quite compact, approximately half of the amount of DDR RAM so that more space saving. This type of memory
Maybe so much that I can say about the function and type of ram memory type
