Assignee: SANDISK TECHNOLOGIES, INC.
Field: Basic communication processes (Electrical engineering)
Classification: CPC H | IPC H

Claim 19:
20. A method, comprising:
activating control circuitry of a first stage level shifter responsive to a transition of an input voltage to the first stage level shifter from a logic low level in a first voltage domain to a logic high level in the first voltage domain, wherein activating the control circuitry causes a first latch of the first stage level shifter to initiate a transition to a first latch state;
maintaining an intermediate voltage of an intermediate node of the first stage level shifter at a logic high level in an intermediate voltage domain while the input voltage is at the logic high level in the first voltage domain;
activating control circuitry of a second stage level shifter responsive to maintaining of the intermediate voltage in the intermediate voltage domain, wherein activating the control circuitry causes a second latch of the second stage level shifter to initiate a transition to a second latch state; and
maintaining an output voltage of an output node of the second stage level shifter at a logic high level in a second voltage domain while the intermediate voltage is at the logic high level in the intermediate voltage domain.
