Abstract
The memory device includes a memory block with memory cells that are arranged in word lines, some of which are reconfigurable word lines that are dummy word lines when the memory block is operating in a one bit per cell mode and are data word lines when the memory block is operating in a multiple bits per cell mode. Circuitry is configured to program the memory cells of a selected word line. The circuitry determines if the selected word line is a reconfigurable word line. If the selected word line is not a reconfigurable word line, the circuitry programs the memory cells of the selected word line with a first programming scheme. If the selected word line is a reconfigurable word line, the circuitry programs the memory cells of the selected word line with a second programming scheme that is different than the first programming scheme.
