A memory model addresses challenges arising from cpu caches and the need for processors to see consistent values. And also compilers and processors may reorder instructions for optimization, making a memory model necessary to handle these cases! 🤯

synchronization mechanisms ensures that memory writes by a thread are made visible to other threads in a predictable manner. 🔎

In #java we have a memory model that define the conditions under which writes to memory by one processor become visible to other processors. ☕️
