Access line disturbance mitigation
Abstract:
Methods, systems, and devices for access line disturbance mitigation are described to, for example, reduce voltage disturbances on deselected digit lines during a read or write operation. Memory cells of a memory device may be couplable with a write circuit including a level shifter circuit, such that changes in voltage on a selected digit line may be controlled via a level shifter circuit of a write circuit associated with a selected memory cell. The write circuit may write a logic state to the memory cell after completing a read operation. One or more write voltages may be applied to or removed from the memory cell via the level shifter circuit, which may control a slew rate of one or more voltage changes on the selected digit line. The slew rate(s) may be controlled via a current driver circuit coupled with a pull-up circuit or a pull-down circuit of the level shifter circuit.
