Abstract
In order to achieve tight and uniform erased threshold voltage distributions in a non-volatile memory system that includes non-volatile memory cells arranged in blocks that have multiple sub-blocks and has an erase process using gate induced drain leakage (GIDL) to generate charge carriers that change threshold voltage of the memory cells, the magnitude of the GIDL is adjusted separately for the sub-blocks.
