Abstract

PURPOSE:To eliminate a need of write and read transfer by directly transferring data from a write register to a read register without passing memory cells. CONSTITUTION:A test circuit part 20 which executes the test processing is connected to a control part 11. For example, a data pattern A is written for the purpose of checking functions of elements other than a cell array of a semiconductor memory. The external test circuit 20 is used to control the control part 11 so that transfer gate groups 5 and 6 are simultaneously opened, and the data pattern A is read in serial. Consequently, processing contents at the time of test are only simultaneous opening of transfer gate groups. Thus, write transfer and read transfer are unnecessary and the test time is shortened.
