A controller is in electrical communication with the plurality of memory cells. The controller is configured to define a multi-block group that includes at least two blocks to be erased. The controller is further configured to simultaneously apply at least one erase pulse to the multi-block group. The controller is further configured to individually and sequentially apply a verify pulse to the blocks. In response to all blocks passing verify, the controller is configured to complete the erase operation. In response to at least one of the blocks not passing verify, the controller is configured to individually and sequentially apply an erase pulse and then a verify pulse to the at least one block that did not pass verify.
