Abstract
A method for forming a memory device is provided. The method includes forming a plurality of memory cells. The method also includes performing a first baking on the memory cells. The method further includes setting a specified current, and after performing the first baking, performing a test process on the memory cells. The test process includes reading the current of the memory cells. When the read current of the memory cells is larger than or equal to the specified current, the test process of the memory cell is done. When the read current of the memory cells is smaller than the specified current, a re-forming process is performed on the memory cells to form a plurality of re-formed memory cells, and then the test process is performed on the re-formed memory cells.
