DRAM syands for Dynamic RAM -- in thsi case each cell is formed from a capacitor and a transistor (the capacitor is formed using transistor level processes -- even better tha tcapacitir is formed on top of the transistor (or vice versa -- I can;t remember). The advantage of DRAM is that it's very dense (close-packed) you gan get a lot of it in a chip. Also it is low on power consumption. The disadvantage is that it's slower than SRAM
In an age of globalization and rapid changes through scientific progress, two of our societies' (and economies') main concerns are to satisfy the needs and wishes of the individual and to save precious resources. Cloud computing caters to both of these.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
