摘要:
The invention relates to a dynamic memory comprising a memory cell array (10), a test controller (12) for testing the memory cell array (10) and an oscillator (14) for controlling the refreshing of said memory cell array (10). According to the invention, said memory includes means (16) for using the oscillator (14) as a time base for the test controller. Hereby, a slow time base is achieved, which may be used for different self-tests of the memory.
