Ram memory meaning (what is it, concept and definition)

What is RAM Memory:

RAM is the main memory of a device where programs and informational data are stored. The acronym RAM means "Random Access Memory" translated into Spanish is " Random Access Memory ".

RAM is known as volatile memory, which means that the data is not saved permanently, which is why when the power of the device ceases to exist, the information is lost. Also, RAM can be constantly rewritten and read.

RAM modules, known as RAM, are members of the hardware that contains integrated circuits that are attached to the printed circuit, these modules are installed on the motherboard of a computer. RAM memories are part of computers, video game consoles, mobile phones, tablets, among other electronic devices.

There are 2 basic types of RAM memory; Dynamic RAM (DRAM) and Static RAM (SRAM), both use different technologies to store data. Dynamic RAM (DRAM) needs to be refreshed 100 times per second, while Static RAM (SRAM) does not need to be refreshed as frequently which makes it faster but also more expensive than dynamic RAM.

In contrast to RAM memory, ROM memory is non-volatile memory since the information contained in it is not erasable when the computer is turned off or with the power cut. For more information you can see our article on ROM memory.

Types of RAM memory

DDR known as SDRAM (Synchronous Dram) is a type of dynamic RAM that is almost 20% faster than RAM EDO. This memory interlaces two or more matrices of internal memory so that while accessing one matrix, the next one is preparing to access, said memory allows reading and writing data at 2 times the buz speed.

DDR2 are enhancements to DDR memory that allow input-output buffers to run at twice the core frequency, allowing 4 transfers to be made during each clock cycle. A DDR memory at 200 real MHZ delivered 400 MHZ nominal, the DDR2 with those same 200 MHZ delivers 800 MHZ NOMINAL.

DDR3 can be 2 times faster than DRR2 memory, DDR3 could theoretically transfer data at an effective clock rate of 800-2600 MHZ, compared to DDR2's range of 400-1200MHZ or 200-533MHZ of DDR2.

Cache or RAM Cache A cache is a special high-speed storage system, it can be either a reserved area of ​​main memory or a separate high-speed storage device. A cache is a part of high-speed static RAM (SRAM) rather than the slow and cheap dynamic RAM (DRAM) used as main memory. Caching is effective because programs access the same data and instructions over and over again.

Within each of these memories there can be different types of storage capacity, that is, they can have a capacity of 1GB, 2GB, 4GB, 8GB.

What is RAM for?

The RAM memory is used to improve the response speed when using a program on the computer since the information that the program needs to make it work is stored in the RAM memory, thus, when executing the program it is transferred to the processor all the instructions that need to be executed making different data transmissions as necessary, consequently, the RAM and the processor interact with each other exchanging the requested data.

The RAM memory stores this information and sends the data that needs to be processed to the processor, therefore, as long as the memory has a higher transmission speed and greater storage capacity, the user will be able to use more programs at the same time and more quickly.
