Based on the identity of Benjamin’s literary theorist and literary critic, the research tries to separate the memory from the complicated philosophical thoughts, and consider it as an independent research object, so as to explore the contents of literature memory. Benjamin believes that the prerequisite of memory is forgetting; the memory mainly draws nourishment from the past literary tradition and forms the star cluster structure by shuttling between the past, present and future. He not only outlines the main process and important factors of memory, but also divides memory dialectically into involuntary memory and conscious memory, which have no absolute boundary and can be converted to each other under certain conditions.
