VOLTAGE CONTROLLER

摘要

A voltage controller is provided that is connected to a voltage inducing circuit which is connected to a static random-access memory (SRAM) cell. The voltage controller comprises a voltage clamping circuit and a pull up circuit. The voltage clamping circuit comprises one or more transistors. The voltage clamping circuit is configured to inhibit a second voltage of a second signal at a second node of the voltage inducing circuit from exceeding a first specified voltage threshold so that a fifth voltage of a fifth signal at a fifth node of the voltage inducing circuit is inhibited from exceeding a second specified voltage threshold. The pull up circuit is configured to maintain the second voltage substantially equal to a specified pull up voltage. The fifth node is connected to the SRAM cell, and a voltage to which the SRAM cell is exposed is thereby controlled.
