Abstract
The VRAM according to the present invention can readily and accurately verify from the outside whether a redundant circuit is being used or not, without provision of a new terminal. The VRAM includes a command signal generating circuit and a switch. The command signal generating circuit responds to a control signal externally received through an external terminal and an address signal to generate a command signal. The switch responds to the command signal from the command signal generating circuit to select between a quote signal from a quote signal generating circuit and a redundant signal from a fuse circuit. The selected signal is provided through one monitor terminal. The quote signal indicates which data stored in the upper side or lower side of a serial register is being provided. The redundant signal activates a redundant circuit.
