Abstract: Technology is disclosed herein for early erase termination as a counter-measure for erase disturb. Multiple erase blocks of NAND memory cells are erased in parallel during an erase procedure. Erasing multiple erase blocks in parallel can place considerable strain on the circuitry that generates the erase voltage. If there is significant leakage current in one of the erase blocks the magnitude of the erase voltage for all of the erase blocks may drop. The erase blocks are tested sequentially for leakage current during the first erase loop while the erase voltage is applied to only the erase block under test. If any erase block fails the leakage current test that erase block is removed from the erase procedure. One or more additional erase loops are then performed with only those erase blocks that passed the leakage current test simultaneously receiving an erase voltage, thereby preventing erase disturb with early termination.
