We had just leveled at 13;000 FT when both MCDU's went 'blank' (just menu prompts; with no FMGC prompt for a few seconds) and both Map displays went blank on the ND's. We were able to re-enter the initialization information and restore Nav/map capability after a few minutes. Just after the FMGC blanked; ATC assigned 7;000 FT. We advised ATC of the loss of Navigation and requested to remain at 13;000 FT; as well as assigned heading. ATC re-assigned us as requested; with a slight change in heading assigned. We were able to re-establish the FMGC within a minute or two and resume the arrival. No emergency was declared and I am not aware of any Priority Handling for Traffic Priority received. The FMGC and IRU drift rate were written up to Maintenance on arrival.
A320 Captain experiences a dual MCDU failure during arrival. Vectors are requested while the reset procedure is performed successfully.
