Abstract
A semiconductor memory includes a first plane that includes a first memory cell array, a second plane that includes a second memory cell array, and a control circuit that includes a first circuit configured to store a first priority for a first operation performed on the first plane and a second circuit configured to store a second priority for a second operation performed on the second plane, and is configured to control the first and second operations based on the first priority and the second priority. When a value of the second priority is higher than a value of the first priority, the control circuit controls the first operation such that a timing of a process executed in the first operation does not overlap with a timing of a process executed in the second operation.
