Abstract: A memory device has an array of memory cells and a controller coupled to the array of memory cells. The controller is configured to determine a program window after a portion of a particular programming operation performed on the memory device is performed and before a subsequent portion of the particular programming operation performed on the memory device is performed. The controller is configured to determine the program window responsive to an amount of program disturb experienced by a particular state of a memory cell. The controller is configured to perform the subsequent portion of the particular programming operation performed on the memory device using the determined program window.
