Abstract
The invention provides a test circuit for n input/output arrays. Each of the n input/output arrays has M pairs of input/output. The test circuit includes M write drivers and M comparing circuits. The iwrite driver provides an itest signal to the iinputs of all of the n input/output arrays, and 1≦i≦M. The jcomparing circuit determines if joutput signals of all of the n input/output arrays are the same, and outputs a jcomparing result correspondingly, and 1≦j≦M. The invention also provides a method of testing n input/output arrays. The invention also provides a storage device.
