"Read level window" refers to a set of candidate read levels that may serve as a read level between two adjacent memory states. In certain embodiments, where the memory cells that are read a read using one or more threshold voltages, a read level window may comprise a set of threshold voltages between a low threshold voltage and a high threshold voltage, with each member of the set of candidate read levels within the read level window comprising a distinct threshold voltage.In another embodiment comprise NAND memory cells, a read level window may comprise a set of threshold voltages between a low threshold voltage and a high threshold voltage, with each member of the set of candidate read levels within the read level window comprising a threshold voltage offset by one or more offset amounts from a default read level, such as a current read level. The offsets from the default read level may be both greater than and/or less than the default read level. A read level window may also be referred to as a “scanning” window.
