1. A non-volatile storage apparatus, comprising:
a plurality of planes of non-volatile memory cells; and
a control circuit connected to the plurality of planes of non-volatile memory cells, the control circuit is configured to:
program memory cells in multiple planes to a set of data states, including performing verification of programming for the data states;
determine that a first plane successfully completed verification of programming for a first data state of the set of data states;
in response to determining that the first plane successfully verified programming for the first data state, check status of verification of programming for a second data state of the set of data states for other planes; and
terminate programming for any plane of the other planes determined to have not successfully verified programming of the second data state when performing the checking status.
