Abstract:
An apparatus includes a sense amplifier that has a sense amplifier differential output. The sense amplifier may be in a first power domain. The apparatus may include level shifting circuitry that has a level shifter differential output. The level shifting circuitry may be coupled to the sense amplifier differential output. The level shifting circuitry may include a first transistor and a second transistor. A first sense amplifier output of the sense amplifier differential output may be coupled to the first transistor, and a second sense amplifier output of the sense amplifier differential output may be coupled to the second transistor. The apparatus may further include a latch to store data. The latch may be coupled to the level shifter differential output. The latch is in a second power domain that is different from the first power domain.
