Abstract:
Methods and systems include memory devices with multiple access lines arranged in an array to form a multiple intersections. Memory cells are located at the intersections of the multiple access lines. Decoders are configured to drive the multiple memory cells via the multiple access lines. Variable biasing circuitry may bias a voltage on an access line of the multiple access lines to change a variable ramp rate of the voltage on the access line. A control circuit is configured to determine a memory cell of the multiple memory cells to be activated. Based at least in part on a distance from the memory cell to a corresponding decoder, the control circuit may set the variable ramp rate of the biasing circuitry.
