Abstract
A test circuit includes a writing unit that outputs m-bit data captured upon receipt of a clock signal, branches the m-bit data n identical m-bit data signals, and stores the n m-bit data signals in a memory device. A function determining unit reads the n m-bit data signals from the memory, compares one of the n m-bit data signals to an m-bit expected value, and determines coincidence or non-coincidence between the n m-bit data signal and an expected value.
