Abstract
The memory device includes a memory block that includes memory cells that are arranged in word lines and memory holes with varying diameters. The word lines are grouped into first and second groups based on memory hole diameter. Circuitry is configured to determine if the selected word line is in the first group or the second group. In response to the selected word line being in the first zone, the circuitry is configured to perform a memory operation using a first set of reference voltages. In response to the selected word line being in the second group, the circuitry is configured to perform the memory operation using a second set of reference voltages. The first and second sets of reference voltages are different for a plurality of data states and are similar for at least one data state at a highest threshold voltage range.
