Abstract
In a low power consumption mode, an internal power supply circuit produces an internal power supply voltage by electrically coupling an internal power supply line to either an external power supply line or a ground line through a transistor. Accordingly, in the low power consumption mode, supply of an operating current to a reference voltage generation circuit, a buffer circuit, an internal power supply voltage generation circuit and a voltage booster circuit is discontinued, allowing for reduction in power consumption of the internal power supply circuit itself.
