The '''KTF11-A memory management chip''' is an optional chip for [[KDF11 CPUs|PDP-11 CPUs]] which use the [[F-11 chip set]]. It implemented the standard [[PDP-11 Memory Management]] (but only the [[PDP-11 Memory Management#Simplified subset|simplified subset]]).

The [[KEF11-A floating point]] chip option requires the KTF11-A, since the [[floating point]] [[register]]s are actually in the KTF11-A (the reason is unknown; the KEF11-A is [[microcode]], but there are enough pins for both the [[data bus]], and the microcode bus).

The KTF11-A chip was the DC304, DEC part # 21-15542-0n (where n is a digit giving the revision; 0 and 1 have been seen).
