Abstract
Apparatus having an array of memory cells and a controller for access of the array of memory cells, wherein the controller is configured to cause the apparatus to apply a reference current to a selected access line, determine a time difference between a voltage level of a near end of the selected access line being deemed to exceed a first voltage level while applying the reference current and the voltage level of the near end of the selected access line being deemed to exceed a second voltage level while applying the reference current, and determine a capacitance value of the selected access line in response to a current level of the reference current, the time difference, and a voltage difference between the second voltage level and the first voltage level.
