摘要:
The invention relates to a dynamic memory having a memory cell array, a test controller to test the memory cell array and an oscillator to control the refreshing of the memory cell array. According to the invention, the memory includes a device for using the oscillator as a time base for the test controller, such that a slow time base is achieved which may be used for different self-tests of the memory.
