Apparatuses, systems, and methods related to sharing a memory resource among physically remote entities are described. A system sharing a memory resource among physically remote entities may enable performance of functions, including automated functions critical for prevention of damage to a product, personnel safety, and/or reliable operation, based on increased access to data that may improve performance of a mission profile. For instance, one apparatus described herein includes a first vehicle configured to determine an availability of processing resources or memory capacity, or both, at the first vehicle based at least in part on a current operating mode of the first vehicle, receive a request from a second vehicle to use at least a portion of the processing resources or the memory capacity, or both, to perform a processing operation at a second vehicle, wherein the request from the second vehicle is associated with insufficient processing capability or memory capacity, or both, at the second vehicle, and perform at least a portion of the processing operation or allow access to the available memory capacity, or both, at the first vehicle in response to the request and based at least in part on determining the availability of the processing resources or the memory capacity, or both.
