What is DRAM?
Dynamic random access memory (DRAM) is a type of random access memory that stores each bit of data in a separate capacitor within an IC. Since real capacitors leak charge, the information eventually fades unless the capacitor charge is refreshed periodically. Because of this refresh requirement, it is a dynamic memory as opposed to SRAM and other static memory. And unlike non-volatile firmware chips, both DRAM and SRAM lose their content when the power is turned off.

What is a semiconductor?
A class of materials, for instance silicon and germanium, whose electrical properties lie between those of conductors (such as copper and aluminum) and insulators (such as glass and rubber). It displays relatively high resistance in pure state and much lower resistance when it contains small amounts of certain impurities.
