Memory is made up of multiple systems including sensory memory buffers like iconic and echoic memory, prospective memory to remember future tasks, episodic memory for autobiographical events, semantic memory for facts and figures, implicit memory for skills, and working memory that can hold about 7 items and transfer information to long-term memory, which is not permanent and also includes spatial memory. Losing one memory aspect does not mean all memory is lost as the brain utilizes different memory systems.
