Abstract:
Technology is disclosed herein for concurrently programming the same data pattern in multiple sets of non-volatile memory cells. Voltage are applied to bit lines in accordance with a data pattern. A select voltage is applied to drain select gates of multiple sets of NAND strings. The system concurrently applies a program pulse to control gates of a different set of selected memory cells in each respective set of the multiple sets of the NAND strings while the select voltage is applied to the drain select gates of the multiple sets of the NAND strings and the voltages are applied to the plurality of bit lines to concurrently program the data pattern into each set of the selected memory cells.
