In the design of computer storage, large numbers of array elements (modules) are often interconnected in a two-dimensional (address X I/O) matrix on an array card. In applications where economic factors outweigh density considerations, it can be desirable to use array modules that are imperfect in a predictable manner. One type of partially good module has M addresses by N input/output (I/O) lines, where P out of N I/O lines are "good". Since there are many possible combinations of partially good modules that can occur, the conventional way to make use of these modules is to design a unique array card interconnection pattern for each type of partially good array module.
