RAM (Random Access Memory) is a form of computer data storage. A random access device allows stored data to be accessed in very nearly the same amount of time for any storage location, so data can be accessed quickly in any random order.
RAM (Random Access Memory) is a form of computer data storage. A random access device allows stored data to be accessed in very nearly the same amount of time for any storage location, so data can be accessed quickly in any random order.
The two main forms of modern RAM are static RAM (SRAM) and dynamic RAM (DRAM). In static RAM, a bit of data is stored using the state of a flip-flop. This form of RAM is more expensive to produce, but is generally faster and requires less power than DRAM and, in modern computers, is often used as cache memory for the CPU.
Both static and dynamic RAM are considered volatile, as their state is lost or reset when power is removed from the system. By contrast, Read-only memory (ROM) stores data by permanently enabling or disabling selected transistors, such that the memory cannot be altered.
