Vortex flow in driven type-II superconductors shows strong memory- and history-dependent effects. Here, we study a schematic microscopic model of driven vortices to propose a scenario for a broad set of this kind of phenomena ranging from rejuvenation and stiffening of the system response, to memory and irreversibility in I-V characteristics.
