Abstract
According to one embodiment, a semiconductor memory device includes: planes each including a memory cell array including memory cells; a comparator configured to, when suspending a write operation and executing a read operation, compare a first plane address corresponding to the write operation with a second plane address corresponding to the read operation; and a controller configured to suspend the write operation and execute the read operation. The controller is configured to, based on an output signal from the comparator, execute the first read operation when the first and second plane addresses match, and execute the second read operation when the first and second plane addresses differ.
