Memory test circuit apparatus and test method

A memory test circuit apparatus and a method are provided. The method may include: compressing first test data output by a first storage array in a memory to generate first compressed data, compressing second test data output by a second storage array in the memory to generate second compressed data, compressing the first compressed data and the second compressed data to generate third compressed data, and outputting one of the first compressed data, the second compressed data and the third compressed data to determine a working condition of each of the first storage array and the second storage array. This method can provide not only a test result on a memory, but also a test result for individual storage array within the memory, which improves the efficiency of a circuit test.
