ABSTRACT:
An output buffer receives a voltage from a first power supply pin receiving an external power supply voltage for operation. Delay circuits included in an array control circuit, a read control circuit, a write control circuit and an internal clock generation circuit receive a voltage from a second power supply pin receiving the external power supply voltage for operation. Thus, a timing control is accurately performed for reading/writing a data signal without being affected by the change in power supply voltage due to an operation of the output buffer.
