Tablets, smartphones propel mobile memory chip market

What is memory?
It is the computer's physical workspace that stores the instructions, programs and data needed to accomplish the tasks executed by the processor for some interval of time, even after electrical power to the computer is turned off.

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.
