  Gravitational wave memory is studied in the context of a certain class of
braneworld wormholes. Unlike other wormhole geometries, this novel class of
wormholes do not require any exotic matter fields for its traversability.
First, we study geodesics in this wormhole spacetime, in the presence of a
gravitational wave pulse. The resulting evolution of the geodesic separation
shows the presence of displacement and velocity memory effects. Motivated by
the same, we study the memory effects at null infinity using the Bondi-Sachs
formalism, adapted for braneworld wormhole. Our analysis provides a non-trivial
change of the Bondi mass after the passage of a burst of gravitational
radiation and hence manifests the memory effect at null infinity. In both of
these exercises, the presence of extra dimension and the wormhole nature of the
spacetime geometry gets imprinted in the memory effect. Since future
gravitational wave detectors will be able to probe the memory effect, the
present work provides another avenue to search for compact objects other than
black holes.
