stupid question - what do these markings on my SDRAM mean

[Cheetah8799]

I have some Micron ram here, and there are different markings on each. I just need some clarification as to what some of the markings mean.

1: 128mb PC100 double sided dimm
This stick has 2-2 on each chip on both sides of the ram. also has -8e on it, which I assume means 8ns.

2: 128mb PC100 double sided dimm
This stick is strange, one side has chips that say 3-2, and the other side has chips that say 2-2. This stick also says -75, which I assume means 7ns.

3: 128mb PC100 double sided dimm
This stick has 1-1 printed on every chip. It also says -75, which i assume means 7ns again.


So, what do these #-# markings mean, and am I correct in assuming that -8e and -75 mean 8ns and 7ns?

This is NOT a stupid question. Those of us who know the answer now, didn't know it in the past and had to ask, Don't put yourself down.
