Abstract
A code checking method for a memory of a printed circuit board is disclosed, and is used to firstly add a check code to a data end of codes, after the codes is written in a memory, then use a timing controller to calculate a checksum of the data of the part of the primary codes and further compare the calculated checksum with the check code, and then output to a probe via a testing pin to display the result of comparison, so as to accomplish an object of checking if the written codes are correct. Thus, work efficiency of checking the codes written in the memory is enhanced.
