The recorders will almost certainly not be serviceable, i. e. they will be destroyed and will not work.

But the memory modules will almost certainly still be readable; they are in some of the toughest enclosures you can imagine, they can protect the memory from shock in excess of 1000 G acceleration, and prolonged hot fires. It is the enclosures' only job to protect the memory modules in precisely this kind of situation. This looks like a head-on crash with a velocity not too different from the Germanwings murder-suicide, so the entire aircraft acts as a crumple-zone reducing the acceleration experienced by the recorders.

The problem will be to find them. This can take weeks.
