  In systems with local gauge symmetries, the memory effect corresponds to
traces inscribed on a suitable probe when a pure gauge configuration at
infinite past dynamically evolves to another pure gauge configuration at
infinite future. In this work, we study the memory effect of 2-form gauge
fields which is probed by strings. We discuss the "string memory effect" for
closed and open strings at classical and quantum levels. The closed string
memory is encoded in the internal excited modes of the string, and in the open
string case, it is encoded in the relative position of the two endpoints and
the noncommutativity parameter associated with the D-brane where the open
string endpoints are attached. We also discuss 2-form memory with D-brane
probes using boundary state formulation and, the relation between string memory
and 2-form soft charges analyzed in [1].
