Abstract
A charge storage memory is configured in a NAND array, and includes NAND strings coupled to bit lines via string select switches and includes word lines. A controller is configured to produce a bias for performing an operation on a selected cell of the NAND array. The bias includes charging the bit line while the string select switches are closed, such as to not introduce noise into the strings caused by such bit line charging. The semiconductor body regions in memory cells that are on both sides of the memory cells in the NAND strings that are coupled to a selected word line are coupled to reference voltages such that they are pre-charged while the word lines of the strings in the array are transitioned to various voltages during the operation.
