What is dynamic random access memory
Computer memory today comprises mainly of dynamic random access memory (DRAM) chips which have been built into multi-chip modules that are, in turn, plugged into slots on motherboard (main circuit board on workstations andpersonal computers). This DRAM is generally referred to as RAM (random access memory) and it constitutes main memory of a computer. The random in random access memory refers to the fact that any location in such memory can be addressed directly at any time. This contrasts with sequential access media, like magnetic tape, which should be read partially in sequence regardless of the desired content.
