Local wordline driver scheme to avoid fails due to floating wordline in a segmented wordline driver scheme

摘要

Embodiments of the invention generally provide a method for accessing a local wordline in a segmented memory. In one embodiment, the method includes, during an access to the local wordline, applying a first voltage to the local wordline via a local wordline driver located at a first end of the local wordline. After the access is completed, a second voltage is applied to the local wordline, wherein the second voltage is applied to the local wordline via a pull-down circuit located at a second end of the local wordline opposite from the first end, and wherein one or more memory cells are attached to local wordline between the local wordline driver and the wordline pull-down circuit.
