Abstract: A method for testing a memory device includes entering a test mode in which multiple memory banks operate in a same manner, allowing a row corresponding to a row address in the multiple memory banks to be activated, latching a bank address and the row address corresponding to the multiple memory banks, writing same data in a column selected by a column address in the multiple memory banks, reading the data written in the writing of the data from the multiple memory banks, checking whether the data read from the multiple memory banks in the reading of the data are equal to each other, and programming the bank address and the row address to a nonvolatile memory when the data read from the multiple memory banks are different from each other.
