摘要： A method for testing a plurality of data bits includes the steps of accepting the plurality of data bits at the test circuit, and comparing first and second data bits from the plurality of data bits to determine if the first and second data bits have a common data value. A first comparison signal is generated responsive to the comparison of the first and second data bits. The first comparison signal has a first logic state when the first and second data bits have a common data value and a second logic state when the first and second data bits have different data values. Third and fourth data bits from the plurality of data bits are compared to determine if the third and fourth data bits have a common data value. A second comparison signal is generated responsive to the comparison of the third and fourth data bits wherein the second comparison signal has the first logic state when the third and fourth data bits have a common data value and the second logic state when the third and fourth data bits have different data values.

摘要： An internal column address generation circuit generates an internal column address by utilizing an asynchronous counter. The circuit includes a column address buffer for synchronizing an initially received external address with an external system clock to generate the internal column address, and for synchronizing a counting bit output signal received at an internal input node with the external system clock to generate the internal column address; and an asynchronous counter connected to an output node of the column address buffer, for generating the bit output signal having the same or opposite phase as/to a phase of the internal column address received from the column address buffer, in response to a carry generation state.
