Abstract
A semiconductor storage device includes a memory string including memory transistors and a control circuit. The control circuit is configured to in response to a first command, perform a first read operation, and in response to a second command received during the first read operation, perform a second read operation. During the first read operation, a voltage of a first selected word line is decreased from a read pass voltage to a first read voltage and then increased to the read pass voltage. During the second read operation, a voltage of a second word line is set to a second read voltage and then increased to the read pass voltage. Voltages of word lines neither selected during the first nor second read operation are maintained between the first and second read operations.
