Understanding memory Sticks

[DCC]

Hi, I would like to know what it means on an Sdram stick 6Mx64. Also is there a way to tell the size of a stick visually, instead of installing??

the capacity is usually displayed right on the memory stick...

What are the codes on the individual chips? (might need a mag. glass to read)
