ABSTRACT:
Embodiments of NAND Flash memory devices and methods recognize that effective column coupling capacitance can be reduced by maintaining a sourced voltage on adjacent columns of an array. Maintaining the columns in a charged state prior to array operations (read, write, and program) reduces current surges and improves data read timing. Devices and methods charge the array columns at pre-charge and following array access operations.
