    Abstract: The present invention relates to a test system (100) interposed between a clock monitor (152) and an internal memory block (125) of a self-timed memory. In an example embodiment, the test system (100) receives an internal clock signal (104) from the clock monitor (152), an external clock signal (CL) and a control signal (CS). A multiplexer (110) of the test system provides in dependence upon the control signal (CS) the internal clock signal (104) to the internal memory block (125) during a normal mode of operation of the self-timed memory and the external clock signal (CL) to the internal memory block (125) during a test mode (108) of the self-timed memory. The test system (100) enables control of the clock cycle of the internal memory block (125) by directly applying the external clock signal (CL) during test mode. Thus, the internal memory block is stressed properly enabling the detection of small delay faults.

    Abstract: A first device delivers a clock offset message to a second device. The second device offsets its data transmission according to the clock offset message. A test pattern is transmitted from the second device to the first device. The first device then checks the received test pattern to determine whether the transmission was successful. The first device can then deliver an additional clock offset message to the second device to instruct the second device to offset its data transmission by a different value than was used previously. The second device again transmits the test pattern and the first device again checks the received pattern. By trying a number of clock offset values and determining which values result in successful transmissions of data, the first device can determine the optimal clock offset value and instruct the second device to use this value for all transmissions.

    Abstract: The access times of semiconductor memories are subject to production-dependent fluctuations, even with identical technological parameters. These fluctuations lead to a certain amount of slow memory chips. By boosting the internal distribution voltage of the slower semiconductor memory by an amount dependent in each case on the semiconductor memory in question, the access time is reduced. The method is applied in semiconductor memories, in particular dynamic semiconductor memories.
