Abstract:
A device includes an array of memory cells having a word line coupled to at least a subset of the array, a queue, and control logic. The control logic: detects a first read command to read first data from a first page of the subset; accesses a second read command in the queue, the second read command to read second data from a second page of the subset; causes a voltage applied to the word line to ramp up to an initial value; causes the voltage to move to a target value; directs a page buffer to sense the first data from a first bit line coupled to the first page of the subset; directs the page buffer to sense the second data from a second bit line coupled to the second page of the subset; and causes the word line to be discharged.
