DRAM - Dynamic Random Access Memory
A type of memory (RAM) widely used in today's PCs. DRAM works differently to SRAM (static RAM) as DRAM needs to be refreshed to continue holding the data. This means a slight loss of speed as the memory refreshes itself with a pulse of current to each of its cells.

The advantage of DRAM modules over SDRAM modules is scale integration.
A single memory cell in a DRAM module consists of one capacitor and one transistor, whereas typical SRAM memory cells are made up of 6 transistors or more, meaning that DRAM modules have a much higher capacity-to-size ratio.
This larger scale integration has made DRAM modules the most popular choice for the main system RAM of modern personal computers and workstations.
