Most users will only need about 8 GB of RAM, but if you want to use several apps at once, you might need 16 GB or more. How much RAM do I need? Why having enough RAM is important, and how to tell ...
When memory devices were relatively expensive compared with the processor, often the RAM delivered with the system was much less than the address capacity of the hardware, because of cost. Sometimes RAM limits can be overcome using special techniques.
Software can "partition" a portion of a computer's RAM, allowing it to act as a much faster hard drive that is called a RAM disk. A RAM disk loses the stored data when the computer is shut down, unless memory is arranged to have a standby battery source, or changes to the RAM disk are written out to a nonvolatile disk.

Spare memory can be utilized as RAM drive for temporary high-speed data storage. As shown in the diagram, traditionally there are two more sub-layers of the primary storage, besides main large-capacity RAM: Processor registers are located inside the processor. Each register typically holds a word of data (often 32 or 64 bits).
Software using unmanaged memory can cause stability problems. Specifically in IBMPC based 32-bit operating systems, some RAM drives are able to use any 'unmanaged' or 'invisible' RAM below 4 GB in the memory map (known as the 3 GB barrier) i.e. RAM in the 'PCI hole'.
If needed, contents of the computer memory can be transferred to storage; a common way of doing this is through a memory management technique called virtual memory. Modern computer memory is implemented as semiconductor memory, [5] [6] where data is stored within memory cells built from MOS transistors and other components on an integrated ...
