ABSTRACT:
A first internal power supply circuit receiving an external power supply voltage for generating a first internal power supply voltage and a second internal power supply circuit receiving the external power supply voltage for generating a second internal power supply voltage are provided within a DRAM. A sense amplifier operates by the first internal power supply voltage. A write driver and a GIO line precharge circuit operate by the second internal power supply voltage. A peripheral circuit operates by the external power supply voltage. As a result, the sense amplifier and the peripheral circuit will not be affected by the operation of the write driver and the GIO line precharge circuit.
