Shared memory and thread are not compareable since both of them relies to different technologies. A Shared memory is one of the methods to implement interprocess communication or IPC, by which different processes or tasks can access the same memory area, to share data between them. A thread or thread of execution is a mechanism by which a process can be split in to multiple simultaneously running pieces of code.
