Abstract
Reducing peak current and/or power consumption during erase verify of a non-volatile memory is disclosed. During an erase verify, memory cells are verified at a strict reference level that is deeper (e.g., lower threshold voltage) than a target reference level. After the strict erase verify, strings of memory cells that pass the strict erase verify are locked out from a next erase verify at the target reference level. Locked out strings do not conduct a significant current during erase verify, thus reducing peak current and/or power consumption.
