  • Publication number: 20100329026
    Abstract: According to one embodiment, a semiconductor memory device includes memory cells, first and second selection transistors, a source line, a temperature monitor, and a source line voltage controller. The memory cells are connected in series between a source of the first selection transistor and a drain of the second selection transistor. The temperature monitor monitors a temperature of the semiconductor substrate. The source line voltage controller applies a voltage to the source line, in a read operation, in such a manner that a potential difference between the source line and the semiconductor substrate increases according to a rise in the temperature monitored by the temperature monitor and that a reverse bias is applied between the source of the second selection transistor and the semiconductor substrate.
