SEMICONDUCTOR DEVICE AND MANUFACTURING METHOD THEREOF

摘要

A semiconductor device and manufacturing method thereof are provided to distinguish data from errors by other causes and maintain the reliability of memorized data high. The first information bit is filled in the information block of the corresponding chip. Here, the first information bit is given to each chip. Each chip is included within 1 shot, the fractional area of the wafer. The second information bit is filled in the second information block of the chip. The second information bit is given at each shot within the wafer. The third information bit is filled in the third information block of the chip. The third information bit is given to the wafer.
