Patent ID: 7952928

Claim:
A method for operating non-volatile storage, comprising: receiving a read command for a selected word line, the selected word line is in communication with a set of non-volatile storage elements along the selected word line, different first and second subsets of non-volatile storage elements are in communication with the selected word line, and one end of the selected word line is closer to the first subset of non-volatile storage elements than to the second subset of non-volatile storage elements; and in response to the read command: identifying the first subset of non-volatile storage elements as including data which is requested by the read command; applying a control gate voltage to the one end of the selected word line, the control gate voltage requires a finite propagation time to propagate throughout the selected word line; determining a time for activating sense components of the first subset of non-volatile storage elements based on the identifying; activating the sense components for the first subset of non-volatile storage elements at the determined time, the determined time is after the control gate voltage has propagated along the selected word line enough to reach all of the non-volatile storage elements in the first subset of non-volatile storage elements; and activating sense components for the second subset of non-volatile storage elements before the control gate voltage has propagated along the selected word line enough to reach all of the non-volatile storage elements in the second subset of non-volatile storage elements.
