Can I use this card’s [Your Turn] effect to gain 1 memory when [EX5-062 Anubismon]'s [When Digivolving] effect trashes this card in my hand and plays it from my trash?
No. This card isn't in the battle area upon the timing when it's trashed, so the [Your Turn] effect doesn't trigger and you don't gain 1 memory.
