Abstract
The present invention discloses a wordline voltage regulation method and system that provides a predetermined voltage as a wordline voltage to a plurality of wordlines during read mode. A supply voltage (Vcc) is regulated and temperature compensated by a wordline driver circuit to provide the predetermined voltage that is lower in magnitude than the magnitude of the supply voltage (Vcc). The wordline driver circuit is activated by an activation circuit when the read operation is initiated. During the read operation, the wordline driver circuit maintains the predetermined voltage during variations in the supply voltage (Vcc) as well as variations in a process load supplied by the wordline driver circuit.
