Abstract
A semiconductor memory device generates a control signal for regulating a potential of an internal power voltage when an extended mode register is set to adjust an operating speed and a tWR (time to write recovery) of a chip. The semiconductor memory device comprises an extended mode register setting unit and an internal power voltage generating unit. When an internal circuit enters into a specific mode for high-speed operation, the extended mode register setting unit outputs a plurality of internal power control signals to regulate a potential of an internal power voltage of the internal circuit. The internal power voltage generating unit generates an internal power voltage by regulating the potential of the internal power voltage in response to the plurality of internal power control signals.
