I am referring to Micron MT46V16M16CY-5B IT:M DDR SDRAM. In its datasheet, I see two different set of pins, VDD-VSS and VDDQ-VSSQ.
What is the difference between them?
The datasheet suggests that the VDDQ and VSSQ have been isolated on the die for improved noise immunity. Does that the VDDQ-VSSQ pair doesn't need a decoupling capacitor between them?
