Abstract
A semiconductor memory device and a method of testing the same are provided. In the method, the semiconductor memory device enters a test mode after receiving a mode selection signal. After the semiconductor memory device enters the test mode, a first word line is activated. Test data are then sequentially written into a plurality of memory cells coupled to the first word line. The first word line is deactivated, and data between each pair of bit lines are latched. A second word line is activated. After the second word line is activated, the data latched between each pair of bit lines are directly written into the memory cells coupled to the second word line.
