Types Of Computer RAM
Learn about the Types Of Computer RAM. RAM otherwise known as Random Access Memory are computer chips that are responsible for storing dynamic data in a temporary manner for the enhancement of computer performance.The use of RAM is also important in printers as well as other devices. This type of memory is volatile which means once the power is switched off its contents are lost. RAM is basically categorized by speed and architecture. With the progress of technology, RAM chips employ novel standards and also become faster so they become compatible with a certain motherboard. The motherboard is only capable of supporting certain memory types and it also possesses a certain limit based on the quantity of RAM it is capable of supporting.
RAM has the capability of improving performance so the amount and type of RAM which a motherboard can support is a very vital factor for choosing a computer. This means if the market has a RAM chip that is better and faster, the buyer will definitely decide on buying a motherboard that has the capability to use it.
The cost of different types of computer RAM varies as to its capacity, type as well as other factors.
Below are some of the types of computer RAM:
CMOS RAM-refers to the small quantity of memory present in your computer as well as in other devices for remembering things such as settings for hard disk. This is one of the types of computer memory which uses a battery so small just enough to give it the capacity it needs for keeping the contents of the memory.
SDRAM– This refers to one of the types of computer RAM which makes the best use of the concept of burst mode for greatly improving performance. It stays along the row which contains the required bit and moves speedily which makes it capable to read every bit when it goes. SDRAM goes faster by five percent compared to EDO RAM and it is the form mostly common in today’s desktops. Its transfer rate at the maximum toward L2 cache is about 528 MBps.
VRAM– Otherwise known as VideoRAM or MPDRAM, is one of the types of computer RAM which is used especially in 3D accelerators or video adapters. VRAM is present in graphics cards and consists of various formats. The display’s color depth and resolution depend on the quantity of VRAM.
RDRAM-This is one of the types of computer RAM which uses a data bus with high speed known as the Rambus channel. Its memory chips work together to acquire a 1,600-MBps data rate or 800 MHz. A great amount of heat is generated by these memory chips because they operate so rapidly.
EDO DRAM -This type of RAM continues searching for the coming bit immediately right after the primary bit’s address is located. It goes faster by five percent compared to FPM. Its transfer rate at the maximum toward L2 cache is about 264 MBps.
FPM DRAM– This is DRAM’s original form. It actually waits until a data bit is located by row and column then proceeds to reading the data bit afterwhich it proceeds to the next. Its transfer rate at the maximum toward L2 cache is about 264 MBps.
DRAM– This is one of the types of computer RAM which consists of memory cells that have the paired capacitor and transistor that requires to be constantly refreshed.
SRAM– This is one of the types of computer RAM which makes use of multiple transistors, basically six to four, for every memory cell but does not contain a capacitor in every cell. It is considered useful for cache.
