The '''KT11-D Memory Management''' was an option for the [[KD11-A CPU]] of the [[PDP-11/40]] which provided [[memory management]]. It did not provide the full [[PDP-11 Memory Management]], but the simplified subset.

It was a [[hex]] card (M7236) which plugged into a dedicated, pre-wrired slot in the [[Central Processing Unit|CPU]]'s [[backplane]]. The KT11-D required the [[KJ11-A Stack Limit Register]] option.

 To install the KT11-D, in addition to installing the card in the backplane slot, a number of [[jumper]]s on other CPU cards have to be adjusted. Two [[capacitor]]s also have to be installed, to modify timing delays in the CPU.
