Abstract:
1. An internal power supply voltage generation circuit for generating an internal power supply voltage at an internal power supply terminal and supplying the internal power supply voltage to a logic circuit, the internal power supply voltage generation circuit comprising: a voltage generation circuit comprising a PMOS transistor which is diode-connected and a first NMOS transistor which is diode-connected; a current source provided between a power supply terminal and the voltage generation circuit; and a second NMOS transistor which is source-follower-connected between the power supply terminal and the internal power supply terminal, including a gate connected to a connection node between the current source and the voltage generation circuit and supplied with a reference voltage, wherein the PMOS transistor is formed by the same manufacturing process as a manufacturing process of a PMOS transistor included in the logic circuit, and wherein the first NMOS transistor is formed by the same manufacturing process as a manufacturing process of an NMOS transistor included in the logic circuit.
