Improving memory is actually avoiding and overcoming forgetting as much as possible. In learning activities as long as the conscious exercise, mastering the rules and methods of memory, you can improve and enhance memory. As long as the memory is focused and concentrated, excluding distractions and external interference, the cerebral cortex will leave a deep memory trace and not easy to forget.

Memory is the immediate state of objective existence, the traces of changes in matter or material systems. In fact, the earliest memory is the memory of nature. But people are accustomed to the brain's memory. It can be argued that the brain memory is a special part of nature's memory, so memory can be divided into two categories: broad memory and narrow memory. Broad memory refers to the memory of nature and the memory of physical activity, while narrow memory refers to the memory of the brain. According to the human convention, the narrow sense of memory is simply called memory.

The content of memory is organized not only by subject but also by time. A new experience, a motor pattern acquired through training, first goes to the working memory for short-term recording, where the information can be read quickly, but with limited capacity. For economic reasons, this information must be purged. Information that is important or that is associated by "correlation" is transported to the medium- and long-term memory. Unimportant information is deleted.

The more frequently the memory content is read, or a movement is repeated, the more refined the feedback, the more the content is evaluated, or the more the movement is optimized. The latter point means that unimportant information is deleted or saved to another location. The depth of memory is related on the one hand to the number of connections between that content and other content, and on the other hand to the emotional evaluation of it.
