Voltage generating circuit for semiconductor integrated circuit device

摘要

A semiconductor integrated circuit includes a node for the power supply voltage for array that is connected to a sense amplifier, a decoupling capacitance connected to the node for the power supply voltage for array, a voltage-down converter connected to the node for the power supply voltage for array and generating a largest voltage stored in a memory cell, and two voltage-down converters connected to the node for the power supply voltage for array and generating a voltage higher than the largest voltage, and boosts the voltage of the node for the power supply voltage for array to attain a voltage higher than the largest voltage in the stand-by state and activates the voltage-down converter generating the largest voltage in operation.
