Abstract: A programming operation is performed on a first set of memory cells addressable by a first wordline (WL), wherein the first set of memory cells are comprised by an open translation unit (TU) of memory cells. It is determined that a second set of memory cells comprised by the open TU are in a coarse programming state, wherein the second set of memory cells is addressable by a second WL. In response to determining that the second set of memory cells satisfies a threshold criterion, a programming state verify level associated with the second WL is reduced by a verify level offset. A programming state gate step size associated with each WL of the open TU is reduced by a predefined value. A programming operation is performed on the second set of memory cells using the reduced programming state verify level and the reduced programming state gate step size.
