Wordline under-driving using a virtual power network

摘要

Systems, methods, and other embodiments associated with improving a static noise margin of memory cells by using charge sharing to under-drive a wordline are described. In one embodiment, a system includes power logic to, in response to a memory request, connect a voltage source with a virtual power network to store an electric charge within the virtual power network based on a voltage from the voltage source. The virtual power network includes a network of interconnects that electrically connect a plurality of driver interconnects. The system includes wordline logic to under-drive a requested wordline of a plurality of wordlines by connecting the requested wordline with the virtual power network to share the electric charge stored in the virtual power network with the requested wordline. The wordline logic under-drives a voltage of the requested wordline to be lower than a source voltage provided by the voltage source.
