Yes. Delirium abilities count the number of card types in your graveyard, not the number of cards. A split card has all characteristics of both its halves if it is in any zone other than the stack, so Commit // Memory is an instant and a sorcery in the graveyard, and thus counts for those two types for delirium.
can I know Commit // Memory count as instant and sorcery for delirium? Thanks!
