A memory management and writing method for managing a plurality of physical units of a memory chip is provided. The present method includes grouping the physical units into a first physical unit group and a second physical unit group, recording and calculating a first erase count of the first physical unit group and a second erase count of the second physical unit group, and calculating an erase count difference between the first erase count and the second erase count. The present method also includes determining whether the erase count difference is larger than an erase count difference threshold when a write command is received. The method further includes executing a switched writing procedure to write data corresponding to the write command into the memory chip when the erase count difference is larger than the erase count difference threshold. Thereby, the lifespan of the memory chip is effectively prolonged.
