ABSTRACT:
A semiconductor memory apparatus including a simple circuit configuration and is capable of randomly accessing fuse data. A fuse cell30including a fuse31is connected to a pair of bit lines of a memory circuit. The fuse31and a fuse data output circuit (which includes a resistor32and an inverter33) are connected to a pair of bit lines BLT and BLB of the memory circuit through a fuse selection switch34. By allowing a column decoder12for selecting a pair of bit lines of the memory cell to also function as a decoder circuit for selecting a fuse, the bit lines of the memory circuit can be used as signal lines for outputting fuse data, whereby the circuit size is reduced and the circuit area is reduced.
