Question about Micron memory

[Avalon]

I was wondering if Micron made any sticks of memory that were PC4000, or if they had memory chips that ran natively at PC4000 speeds? I remember hearing that Crucial was the brand name that Micron used to sell sticks of memory, but their memory chips specifically were Micron brand, or am I confused? Thanks for any input.

Crucial is a division of Micron that sells memory modules and other products. The memory modules usually use Micron chips but I have seen others.
Micron and Crucial are both based out of Boise Idaho.
