Integrated circuit memory devices include multiple voltage regulators configured to generate respective boosted voltages, which are provided to a memory cell block. A first voltage regulator is configured to increase a well voltage (Vwell) from a first level to an elevated second level during a pull-up time interval when a boosted well voltage level is required within a memory cell block. The increase in the level of the well voltage occurs in response to a transition of a trim signal (Trim) received at an input of the first voltage regulator. A second voltage regulator is also provided. The second voltage regulator is configured to increase a word line voltage (Vwl) from a third level to an elevated fourth level during the pull-up time interval, in response to the transition of the trim signal and in response to the well voltage. A memory cell block is provided, which is configured to receive the well voltage and the word line voltage during the pull-up time interval.
