DRAM (Dynamic Random Access Memory) is type of volatile memory. Now-a-days, semiconductor memory is capable to store large data in small area. In past SRAM (Static RAM) is more preferable as compared to DRAM because of its high speed operation, large noise margin and logic compatibility. However, due to its large cell area and high power consumption, SRAM has limitations when expanding the array size beyond a certain level in process variation. This paper reviews the history of RAM from SRAM to DRAM.
