    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 method (300) and apparatus for testing correct operation of a page decoder in a memory is provided. In one implementation, the method includes erasing the memory (302) to reset all memory cells associated with each of the N pages in the memory, and iteratively generating a unique bit sequence of M bits (304) and programming the unique bit sequence into a plurality of the N pages (306) at a given time until each of -the N pages contains a unique bit sequence relative to other pages in the memory (308). Responsive to each of the N pages having a unique bit sequence, the method further includes using the page decoder to read out each unique bit sequence associated with the N pages to verify correct operation of the page decoder (310).

    Abstract: The proposal is for a self-testing device for storage arrangements, decoders or the like for use in on-line operation, in which the word lines and/or the column lines of a storage matrix are connected to a test matrix (17). An error detector (27) generating an error signal when more than one word lines are active simultaneously is connected to the test matrix (17). As, for the most frequently occurring errors in the decoder, several word or column lines are activated, it is possible with this relatively simple and economically produced test matrix to perform a simple self-test during on-line operation.
