An adjustable memory track assembly for a vehicle seat has a lower rail adapted to be secured relative to a vehicle frame, and an upper rail adapted to support the seat for fore/aft sliding movement relative to the lower rail. The adjustable memory track assembly also has a track lock assembly operable via a first actuator between a locked, engaged state wherein relative movement between the lower and upper rails is resisted, and an unlocked, disengaged state wherein the seat can be slid to and then locked in a user-selected position. A memory module is operable via a second actuator to record the user-selected position. The second actuator is also operatively connected to disengage the track lock assembly to allow forward movement of the seat from the user-selected location to a forward location, and thereafter allow rearward movement of the seat back to, but not past, the user-selected location. The adjustable memory track assembly is characterized in that the memory module is provided with a blocking element to prevent rearward movement of the seat past the user-selected position independent of the locking state of the track lock assembly.
