Abstract:
Technology is disclosed herein for sensing memory cells while compensating for resistance along an electrical pathway between a voltage driver and a control line connected to the memory cells. A control circuit provides a voltage from the voltage driver over a first electrical pathway to a control line in a first block and a second electrical pathway to a control line in a second block. The control circuit senses first memory cells in the first block and the second memory cells in the second block while compensating for a difference in resistance of the first and second electrical pathways. In one aspect, the control circuit discharges a first sense node for a different period of time than a second sense node to compensate for the difference in resistance. Compensating for the difference in resistance compensates for a different IR drop of the electrical pathways.
