Abstract
A memory device includes a memory array including memory blocks, and a control circuit coupled to the memory array. The control circuit is configured to when multi-pass program operations are performed, during a non-last pass program of the memory cells in a first memory sub-block of a first memory block, determine verify loop counts of verify operations after programming the memory cells in the first memory sub-block of the first memory block to one or more first target program states; and when programming the memory cells in a second memory sub-block of the first memory block to the one or more first target program states using the same program and verify conditions as for the first memory sub-block of the first memory block, during the non-last pass program, not perform at least the verify operation corresponding to the last of the verify loop counts.
