More Information
Summary:The invention discloses a memory structure and a method capable of performing characterization of output data paths without accessing the main memory array. The memory structure includes: a plurality of output data paths; a plurality of registers coupled to the output data paths. The registers include: at least a first pattern register and a second pattern register, for respectively storing a first data pattern and a second data pattern; and at least a first mapping register, for storing a plurality of binary values, wherein each binary value indicates whether the first data pattern or the second data pattern should be mapped to a corresponding output data path. According to the invention, the characterization of the integrity of the read signals can be carried out, the signal cannot be disturbed by the noises and limited by the signal timing sequence, and therefore the correct signal reading results can be achieved.
