Abstract
A programmable data exchange device, that is coupled between one memory and one external system, in which the memory features several data I/O pins, and some of them have defects, some perfect, comprises: one data exchange unit with the first multiple data I/O pin and the second multiple data I/O pin, in which the first multiple data I/O pin is coupled to data I/O pin of the memory, and the second multiple data I/O pin is coupled to the external system, and the data exchange unit includes one memory unit for storing connection data of the first multiple data I/O pin which should correspond to the second multiple I/O pin; one testing unit coupled to the external system and the data exchange unit for controlling the data exchange in order to conduct test to the memory, and disabling the pins of the first multiple data I/O pin of the data exchange unit, which are coupled to data I/O pin of defect data I/O pin in the memory, and among the second multiple data exchange pin which is not coupled with perfect data I/O pin in the memory, and controlling storage data access in the memory unit of the memory exchange unit; one controlling unit coupled to the external system and the data exchange unit for controlling data transmission direction of the data exchange unit.
