Abstract:
In order to have different subsets of memory cells of a non-volatile memory system erase at the same speed, it is proposed to perform erasing by separately controlling the speed of erase for the different subsets in response to observing speed information for the subsets during the erasing.

Claim (Index 13):
A system, comprising:\n a plurality of non-volatile memory cells including a group of connected memory cells arranged in multiple sub-groups of connected memory cells, each sub-group of connected memory cells has its own set of one or more selection lines with respect to other sub-groups of connected memory cells; and peripheral circuits connected to the plurality of non-volatile memory cells and configured to apply a series of erase voltage bursts to the group of connected memory cells, separately erase verify each of the multiple sub-groups after a first erase voltage burst, characterize erase progress after the first erase voltage burst for each of the multiple sub-groups, adjust one or more voltages on the selection lines of the sub-groups based on the characterization of the erase verify to cause erase operations of the sub-groups to converge towards completing at a same time, and erase verify only a subset of the multiple sub-groups as a representative of all of the multiple sub-groups in response to the one or more additional erase voltage bursts.
