SHARED-BIT-LINE BIT LINE SETUP SCHEME

机译:共享位线位线设置方案

摘要

Methods for operating a non-volatile storage system utilizing a shared-bit-line NAND architecture are described. A shared-bit-line NAND architecture includes one or more pairs of NAND strings, wherein each pair of the one or more pairs of NAND strings shares a common bit line. In some embodiments, a pair of NAND strings includes an odd NAND string adjacent to an even NAND string. Prior to programming a memory cell associated with the even NAND string, an odd channel associated with the odd NAND string (i.e., the NAND string of the pair that is not selected for programming) is precharged to a bit line inhibit voltage, floated, and then boosted to a second voltage greater than the bit line inhibit voltage as an even channel associated with the even NAND string is precharged. Subsequently, the odd channel may be boosted (e.g., via self-boosting) prior to programming the memory cell.
