A small explanation about SDRAM and DRAM
RAM , also called random access memory, which is a type of a computer memory that can be accessed randomly. RAM can access to data much more faster than the hard drive which could directly access the data stored inside, which allows the computer to run much more faster.
There are two types of RAM; DRAMs and SDRAMs .
DRAM also called dynamic ram is the ram we use mostly in our personal computer.It constantly needs to be refreshed(re energized) to prevent loss of contents.
SDRAM also called static dynamic ram, is the ram which is mostly inside of a CPU. It is called static for because of it does not need to be constantly to refresh/re energize.
SDRAM is expensive and also faster than DRAM. For example a 512 megabyte of SDRAM can access data faster than a 8 gigabyte of DRAM.
