Abstract
An error detecting circuit of a semiconductor apparatus, comprising: a fail detecting section configured to receive 2-bit first test data signals outputted from a first block and 2-bit second test data signals outputted from a second block, disable a first fail detection signal when the 2-bit first test data signals have different levels, disable a second fail detection signal when the 2-bit second test data signals have different levels, and disable both the first and second fail detection signals when the 2-bit first test data signals have the same level, the 2-bit second test data signals have the same level, and levels of the 2-bit first test data signals and the 2-bit second test data signals are the same with each other.
