Memory consistency models traditionally specify the behavior of shared memory concurrent hardware. Hardware behavior drifts away from traditional sequential reasoning, thus exhibiting behaviors that are termed as "weak". Weaker consistency models allow for more concurrent behaviors, thus justifying hardware optimizations such as read/write buffers. In parallel, weaker memory models for software allow more compiler optimizations (transformations). However, this "more" may not be strict: certain safe optimizations in stronger models are rendered unsafe in ones weaker than them. We identify properties that must hold among a pair of weak and strong memory models to guarantee this. We propose a framework using which we could build such models, showcasing our results in allowing Read Read reordering over Sequential Consistency (SC). We also show how to partially retain our desired property for a pair of models, placing constraints on the set of transformations or equivalently, on program structure. Lastly, we discuss the potential advantage of designing models satisfying such properties.
