RAM (random access memory) is memory that the computer can use “randomly”, it is memory that is kept available for programs to use – available memory is measured in gigabytes (Go). and speed is measured in megahertz. This means that the more RAM a computer has, the faster it will run and be able to run more software at the same time. This memory is called volatile memory because it is lost when the system is turned off, that's why we save our games/work and they go to storage – the hard drive. Unlike ROM (read only memory), which cannot be lost or modified. The ROM performs necessary basic functions such as booting a computer system because it contains the BIOS. The BIOS on the ROM chip is a set of software utilities that start the system every time it is turned on while checking the hardware configuration against the configuration data, called the POST (power-on self-test) process. ).

On the other hand, static RAM (SRAM) is made up of 4/6 transistors plus wiring and keeps its data in its memory for as long as the computer is powered, so it does not need to be refreshed, this which makes it faster than DRAM. but also more expensive. Rambus dynamic RAM uses a RAM controller and bus connected directly to the processor and other devices that need it and provides a constant memory bandwidth of 1.6 GB per second that operates at 800 MHz; this type of memory was useful on earlier gaming platforms like the N64. However, modern memory has used variations of these types to create faster and more efficient forms of RAM. SDRAM Synchronous Dynamic RAM was a 1990s variant that allowed memory responses to be synchronized with control inputs in data buses – this meant it could queue processes while a process was running. Keep in mind: this is just an example.

DDR versions of RAM have been upgraded to their fourth version today by expanding on the existing idea, DDR4 RAM allows up to twice as many GB (4-16 GB), doubled data rates and a Lower voltage required to operate. For examples of different RAM usage, the Samsung Galaxy S7 uses 4 GB of DDR4 RAM and the Nintendo 3DS XL uses 128 MB of FCRAM (a type of SDRAM developed by Fujitsu and Toshiba). While the PS4 Pro uses 8GB of GDDR5 RAM, a type of RAM that only works for graphics cards, desktop computers can have as much RAM as the motherboard and operating system can support, but adding more than necessary does not make a computer more, 108(9), 1679-1685.
