Abstract
A memory device includes a memory array comprising memory cells and control logic. The control logic performs operations including: causing a first erase pulse to be applied to a memory line of the memory array to perform an erase operation, the memory line being a conductive line coupled to a string of the memory cells; suspending the erase operation in response to receipt of a suspend command during a ramping period of the first erase pulse; recording a suspend voltage level of the first erase pulse when suspended; causing the erase operation to be resumed in response to an erase resume command; selectively modifying a pulse width of a flattop period of a second erase pulse based on the suspend voltage level; and causing the second erase pulse to be applied to the memory line during a resume of the erase operation.
