Abstract

A non-volatile memory system is configured to perform a multiplane erase process that concurrently erases groups of memory cells in multiple planes. Based on that multiplane erase process, the memory system determines that a first group of memory cells in a first plane of the multiple planes is slow to erase. As a result, the system will perform one or more multiplane erase processes for the groups of memory cells in multiple planes without erasing the first group of memory cells in the first plane as part of the multiplane erase process(es).
