Non-volatile memory with enhanced early program termination mode for neighbor plane disturb

Abstract

A non-volatile storage apparatus comprises memory cells organized into multiple planes. To prevent one plane from disturbing another plane while concurrently programming memory cells in a first plane and memory cells in a second plane, the system determines that the memory cells in the second plane are programming slower than the memory cells of the first plane, tests whether the memory cells in the first plane have threshold voltages greater than a test level that is higher than a target verify level, determines that the memory cells in the first plane failed programming if more than a maximum number of the memory cells in the first plane have threshold voltages greater than the test level, and determines that the memory cells in the second plane failed programming if not more than a maximum number of the memory cells of the fast plane have threshold voltages greater than the test level.
