  Memory effects can have a profound impact on the resistivity of semiconductor
systems, resulting in giant negative magnetoresistance and MIRO phenomena. This
work opens the discussion of the memory effects in 3D conducting systems
featured by the presence of the extended one-dimensional defects, such as screw
dislocations or static charge stripes. We demonstrate that accounting for the
memory effect, that is the capture of electrons on collisionless spiral
trajectories winding around extended defects, leads to the strong negative
magnetoresistance in case when the external magnetic field direction becomes
parallel to the defects axis. This effect gives rise to a significant
magnetoresistance anisotropy already for an isotropic Fermi surface and no
spin-orbit effects. The proposed resistivity feature can be used to detect
one-dimensional scattering defects in these systems.
