Abstract
A memory device comprises memory elements that are arranged in an array. The array includes rows associated with wordlines and columns associated with bitlines. The memory elements in a row share a wordline and memory elements in a column share a bitline. For each wordline, a wordline driver circuit is associated with the wordline. The memory device comprises a boost circuit that has an output coupled to the wordline driver circuits. The boost circuit is configured to provide a negative voltage to the wordlines during a read operation of the memory device such that unselected wordlines are held at a negative voltage below a ground potential while a selected wordline is held at a supply voltage during the read operation.
