My opponent has this Digimon in play. What happens if an effect is activated that causes you to gain memory on activation and lose memory at end of turn? (i.e. [BT1-090 Gravity Crush], [BT1-021 MetalGreymon], [BT1-040 WereGarurumon], [BT1-058 Chirinmon], [BT1-075 Digitamamon], etc.)

Official Ruling
You can't use Option/Digimon card effects to gain memory, but you can still lose memory if a card effect specifies as such. At the end of the turn, you’ll lose memory as specified by each effect.
