Chips

[matiasht]

Greetings everyone at this wonderful forum!

I read a lot of your very interesting articles and I have to say, Kudos!

The anatomy of hardware is one of the thing I'm interested the most, so I have this

question:

What is the difference between a buffer chip and a RAM chip? for example the one printed in

the circuit board of a DVD Burner, what other devices have both chips?

Is there any article where I can read how the DVD Burner works?

As I have said before, Kudos! on this forum, and I wait anxious for your valuable reply!

Dismissed.

Start here http://en.wikipedia.org/wiki/DVD_recorder, there are links to other part from there.

Buffer chip, RAM chip, nothing different except use and speed. I guess there is a lot of differences in the tech used to make them, just like there is a huge difference between a 386 cpu and a i7, but they are basically the same. Buffers hold data for use between the hard-drive/PC RAM and the burner, while RAM holds the data between the CPU and hard-drive.

But the DVD Burner has a RAM chip too, that's why I'm confused...

Don't know exactly what it has on the drive, but it would not be RAM like the PC ram. It's probably for the buffer memory.

I don't think like that either, but, that would be two chips:

-Buffer chip

-RAM chip

I'm almost sure that it has something to do with the buffer one of course, just as you said, a buffer memory, where data is before going to the buffer chip.
