Abstract
A reservoir capacitor array circuit capable of allowing an internal voltage to be maintained stably, comprises a plurality of reservoir capacitors, each of the reservoir capacitors including a switch element which is connected between a power source voltage and a prescribed node and switched in response to a test enable signal which is enabled depending on a test mode signal or whether the fuse is cut or not, and a capacitor connected between the node and a ground voltage.

A reservoir capacitor array circuit capable of allowing an internal voltage to be maintained stably, the reservoir capacitor array comprising a plurality of reservoir capacitors, and each of the reservoir capacitors comprising:
- a switch element connected between a power source voltage and a prescribed node and switched in response to a test enable signal which is enabled depending on a test mode signal or whether a fuse is cut or not;
- and
- a capacitor connected between the node and a ground voltage.
A reservoir capacitor array circuit, comprising:
- an enable signal generating unit including a fuse and at least one enable signal generator which generates a test enable signal determined to be enabled depending on a test mode signal or whether a fuse is cut or not;
- and
- a reservoir capacitor array including a plurality of reservoir capacitors, wherein each of the plurality of reservoir capacitors has capacitance determined in response to the test enable signal.
