My opponent uses [EX1-068]/[Ice Wall!] while one of my Digimon is affected by this card's "isn't affected by your opponent's Option cards" effect. If it becomes my next turn and this card's effect expires, will that Digimon have the "<When Attacking> Lose 2 memory" effect?
Yes, this card's "isn't affected by your opponent's Option cards" effect expires while the effect of [EX1-068]/[Ice Wall!] is still active, so that Digimon will have [EX1-068]/[Ice Wall!]'s "<When Attacking> Lose 2 memory" effect.

My opponent uses [EX1-068]/[Ice Wall!] and I activate this card's "isn't affected by your opponent's Option cards" effect on one of my Digimon that has "<When Attacking> Lose 2 memory". What happens with the "<When Attacking> Lose 2 memory" effect in such cases?
Since that Digimon isn't affected by your opponent's Option cards anymore, [EX1-068]/[Ice Wall!]'s "<When Attacking> Lose 2 memory" effect ends.
