A power-up circuit for an SRAM, particularly a loadless 4-T SRAM cell having PMOS access transistors. The power-up circuit disables a current path to the digit lines in an array of SRAM cells during power-up of the SRAM. As a result, the SRAM cells cannot draw power from the digit lines during power-up if voltages on word lines in the array during power-up cause access transistors for the SRAM cells to become conductive.
