An integrated circuit with memory can operate with reduced latency between consecutive operations such as read operations. At a first time, a first operation command is finished on a memory array on an integrated circuit. At a second time, a second operation command is begun on the memory array. A regulated output voltage from the charge pump is coupled to word lines in the memory array. From the first time to the second time, a regulated output voltage is maintained at about a word line operation voltage such as a read voltage.
