A semiconductor device has a least one logic circuit and at least one memory macro cell having a plurality of memory cell array blocks each composed of a plurality of memory cells. Addresses for designating the memory cell array blocks in test are selected among external addresses by a switching signal. The semiconductor device may have a plurality of memory macro calls having a plurality of memory cell array blocks each composed of a plurality of memory cells. The memory macro cells are switched in configuration as having the same length of rows or columns between the memory macro cells in test. The configuration is different from a configuration of row and column for a regular operation.
