delete

We all know that if you want to completely delete files from HDD, you have to use a special erase algorithm in order to make it impossible to read it back. But what with the memory cards? Do they need the same algorithms to ensure that no one could read it back? (it has a completely different structure to store data, and I don't know what the case here with secure delete)
