The idea of IDE, as my understanding, is the controller that existed as an ISA card was moved onto the actual drive, and then what became the controller was mostly just extending the ISA bus over to the drive.
I actually have an IDE "controller" somewhere which is just a tiny PCB with an ISA connector on one side and a 40 pin IDE connector on the other, along with a couple of ICs (presumably buffers/latches, but I don't know without finding it). It's somewhat unusual, given that IDE ports were normally included as part of multi-I/O boards, or (a little later) often incorporated into the motherboard.
