A semiconductor integrated circuit includes a memory cell array, a read circuit that reads test data from the memory cell array, a parallel test control circuit, a bit organization address control circuit, and a parallel test circuit. The parallel test control circuit, in response to a wafer test flag signal, a package test flag signal, and a bank activation signal, generates a first control signal and a second control signal. The bit organization address control circuit, in response to the wafer test flag signal, the package test flag signal, the bank activation signal, and a bit organization information signal, generates a third control signal. The parallel test circuit, in response to the first and second control signals, determines whether all bits of the test data read have the same logic levels. The first, second, and third control signals determines where the test data are read from in the memory cell array.
