Abstract
According to an embodiment, a memory system includes a nonvolatile memory and a memory controller. The nonvolatile memory includes storage areas. The memory controller counts a first number that is the number of uncompleted requests generated in a first time section for read operations to be executed on a first storage area. In a second time section subsequent to the first time section, the memory controller waits until the first number becomes zero without executing an erase operation on the first storage area while the first number is not zero, and executes the erase operation on the first storage area in response to the first number becoming zero.
