DDR Memory

Am I Right DDR1. has 184 Pins?

And if it is ECC does it have more Pins?

 

I ask because if a SIMM was None Parity it was 30 Pins.
But if it was Parity it was 72 Pins.

So I thought if a DIMM was ECC the Pin Count would go up.

So if a DIMM is ECC or None ECC why does it's Pin Count Stay the same?

Thanks for all the help.

 

And am I Right DDR2. and DDR3. both have 240 Pins?

 

For use in computers, DDR2 SDRAM is supplied in DIMMs with 240 pins and a single locating notch. Laptop DDR2 SO-DIMMs have 200 pins

DDR3 dual-inline memory modules (DIMMs) have 240 pins and DDR3 SO-DIMMs have 204 pins.

Found both answers here

Now I want to know if I have the Bandwidth down Right?

DDR Memory Transfers 64 Bits on the Rise and Fall of every Cycle.

So in One Cycle it Transfers 128 Bits.

And if it it DDR2. and it says 800 MHz on it.
Then it is Transfering 128 Bits X 800 = 96,000,000 Bits a SEC Right?

 

Do I have this Right?
