摘要:
A semiconductor memory device includes a power supply circuit configured to supply an intermediate voltage between a power supply voltage and a ground voltage to each of a plurality of memory cells. The power supply circuit firsts generates a first intermediate voltage between the power supply voltage and the ground voltage and a second intermediate voltage between the power supply voltage and the ground voltage. In response to a first control signal, the first intermediate voltage is supplied to an output node and the second intermediate voltage stops. A connection control circuit connects the first output node and a second output node when the second intermediate voltage generating circuit stops its operation.
