  • Method and apparatus for testing memory cells for data retention faults
    Patent number: 6681350
    Abstract: A method for testing memory cells for data retention faults is disclosed. A first logical value is stored in a first cell, and a second logical value is stored in a second cell of a memory device. The second cell shares the same column with the first cell. The bitlines associated with the first and second cells are prevented from being precharged before the second cell can be read. After the second cell has been read repeatedly, the first cell is read, and the bitlines associated with the first and second cells are precharged. At this point, a data retention fault is determined to have occurred if the first cell does not contain the first logical value.
