Abstract: Various implementations described herein are directed to an integrated circuit having a wordline driver coupled to a bitcell via a wordline. The integrated circuit may include a read assist transistor coupled to the wordline between the wordline driver and the bitcell. While activated, the read assist transistor may generate an adaptive underdrive on the wordline, the level of which depends on the process, temperature and voltage of operation of the memory, when the wordline is selected and driven by the wordline driver.

Abstract: Various implementations described herein are directed to an integrated circuit. The integrated circuit may include dummy wordline circuitry having a dummy wordline driver coupled to a dummy wordline load via a dummy wordline. The integrated circuit may include underdrive circuitry coupled to the dummy wordline between the dummy wordline driver and the dummy wordline load. The underdrive circuitry may generate an underdrive on the dummy wordline when the dummy wordline is selected and driven by the dummy wordline driver.
