    摘要: The present invention relates to a semiconductor memory device incorporating a column redundancy circuit using a decoded fuse. The column redundancy circuit is capable of designating a repaired address during a parallel test mode of memory operation when an address input is a "don't care," and it is particularly useful in a multiple input/output memory architecture which uses one column select per I/O line. The column redundancy circuit includes: transmitting means comprised of the data input/output lines for transmitting the data of the memory cell; column decoder and input/output control circuits connected to the transmitting means and decoding a column address input to input data; a circuit connected to the transmitting means and outputting a given signal to the column decoder and input/output control circuits in response to a plurality of output signals output from fuses and a signal for controlling the transmitting means; a plurality of decoded fuse circuits, the levels of which are determined by one fuse connected to the circuit; multiplexers for selectively transmitting data from one of the data input/output lines to a specific data bus line among a plurality of data bus lines; and a decoding circuit which receives the outputs of the decoded fuse circuits and generates a redundancy signal.

    摘要: The time required for testing high-density semiconductor memory devices is reduced by circuits and methodology for rapidly writing test data bits into the memory array. A common word line enable signal is arranged to turn on all of the word lines in the array simultaneously. Test data bits are applied to the array by gating them onto the I/O lines so that separate test bit lines are not required. A fast test enable signal gates the test bits onto the I/O lines in all columns of the array simultaneously, so that all of the memory cells receive test bits at one time. The new circuitry has the further advantages of reduced area and capacitance, the latter further contributing to reducing the test data write time.
