16 Facts About Physical memory

In contemporary usage, Physical memory is usually semiconductor storage read-write random-access Physical memory, typically DRAM or other forms of fast but temporary storage.

Core Physical memory remained dominant until the 1970s, when advances in integrated circuit technology allowed semiconductor Physical memory to become economically competitive.

Spare Physical memory can be utilized as RAM drive for temporary high-speed data storage.

Main Physical memory is directly or indirectly connected to the central processing unit via a Physical memory bus.

Many types of "ROM" are not literally read only, as updates to them are possible; however it is slow and Physical memory must be erased in large portions before it can be re-written.
