摘要： A semiconductor memory device has an external terminal receptive of a voltage for switching an operation mode. A protective transistor is connected between the external terminal and a ground. The protective transistor has a drain region and a gate electrode surrounding the drain region. A voltage detection circuit detects a voltage of the external terminal and outputs a switching signal for switching a first operation mode to a second operation mode when a value of the detected voltage is equal to or higher than a preselected voltage value.

摘要： Provided is a power supply switching circuit capable of efficiently supplying a desired voltage among a plurality of voltages to a load. In the case of a P-type semiconductor substrate, N-type MOS transistors are provided between a load and an AC adapter and between the load and a battery, and hence no parasitic diode exists between the load and the AC adapter or the battery, resulting in no current path due to the parasitic diode. Thus, when the AC adapter and the battery are connected to the power supply switching circuit, the N-type MOS transistor is turned off, whereby the current path between the battery and the load is cut off completely and the N-type MOS transistor is turned on. Accordingly, the battery cannot supply a voltage to the load while only the AC adapter can supply a voltage to the load.
