RAM, DRAM, and SDRAM
WHAT IS RAM?
RAM (Random Access Memory) -one of the most important parts of a computer, primary memory, or temporary storage, is a hardware device that allows information to be stored and retrieved on a computer. It is stored on the motherboard in modules that are called DIMMs(Dual Inline Memory Module).In order for a program to run, data needs to be loaded into RAM. Ram requires constant electrical power to store data.
The general data cycle that CPU and memory storage have in between is like this:
- the data or program is first stored on the Hard drive
- From there, it is loaded into the ram. And once it is loaded into Ram can now access the data or run the program.
- After all of this, data or programs finally is stored at the CPU.
Fact:
Increasing the RAM will make the computer run faster.
DRAM and SDRAM
RAM is usually associated with DRAM — which is a type of memory module.DRAM(Dynamic Ram) is a memory that contains capacitors and transistors. A capacitor is like a small bucket that stores electricity and in these capacitors the bit of information such as a 1 or 0 are hold. Because Capacitors do not hold charge for very long, each time they must be dynamically refreshed often otherwise; they will forget the information that they are holding. DRAM operates Asynchronously with the system clock, which basically means that it runs slower than the system clock.
SDRAM-another type of memory is called SDRAM. It stands for Synchronously Dynamic Ram and used today in RAM DIMMS. The main difference between DRAM and SDRAM is speed. Also, SDRAM does not have any capacitors. SDRAM operates synchronously with the system clock which is for better control limiting. And it is the reason why SDRAM is faster than DRAM.
