Abstract:
Systems, methods, and apparatus related to spike current suppression in a memory array. In one approach, a memory device includes a memory array having a cross-point memory architecture. The memory array has access lines (e.g., word lines and/or bit lines) configured to access memory cells of the memory array. Each access line is split into left and right portions. Each portion is electrically connected to a single via, which a driver uses to generate a voltage on the access line. To reduce electrical discharge associated with current spikes, a first resistor is located between the left portion and the via, and a second resistor is located between the right portion and the via.
