The invention relates to a charged particle multi-beamlet lithography system for exposing a target using a plurality of beamlets. The system has a beam generator, a beamlet blanker, and a beamlet projector. The beam generator is configured to generate a plurality of charged particle beamlets. The beamlet blanker is configured to pattern the beamlets. The beamlet projector is configured to project the patterned beamlets onto the target surface. The system further has a deflection device. The deflection device has a plurality of memory cells. Each memory cell is provided with a storage element and is connected to a switching electrode of a deflector.
