Some embodiments include apparatuses and methods for activating a signal associated with an access line coupled to different groups of memory cells during a memory operation of a device, and for sensing data lines of the device during different time intervals of the memory operation to determine the value of information stored in the memory cells. Each of the data lines can be coupled to a respective memory cell of each of the groups of memory cells. In at least one of such apparatuses and methods, the signal applied to the access line can remain activated during the memory operation.
