Abstract:
Embodiments disclosed herein relate to level shifters of a memory device. Specifically, the level shifters include a first series arrangement of transistors to offset a first transistor. The level shifters also include a second series arrangement of transistors to offset a second transistor. The first series arrangement is opposite the second series arrangement. The output of the first series arrangement is coupled to a first pull-up transistor and configured to cut off a pull-up of the first pull-up transistor to a first voltage. The output of the second series arrangement is coupled to a second pull-up transistor and configured to cut off a pull-up of the second pull-up transistor to the first voltage. The first series arrangement and the second series arrangement are coupled to a second voltage at different times. The series arrangements of transistors enable faster level shifting over conventional level shifters.
