DRAM (Dynamic Random Access Memory) The most common type of computer memory. DRAMs hold data for a relatively brief period of time and need to be refreshed at regular intervals. DRAMs are measured by access time (in nanoseconds, or ns) and storage capacity (in megabytes, or MB).
Computers have various types of memory. Read-only memory (ROM) contains the instructions for what needs to happen when a computer is powered on. The data in ROM cannot be modified, or only with great difficulty, since these instructions do not need to be changed very often.
