POWER SUPPLY CONTROLLING DEVICE

摘要

PURPOSE: A power voltage supply controller for supplying power voltage with a semiconductor memory is provided to supply power voltage supply capability supplied to the semiconductor memory and prevent the formation of forward bias pass generated in a memory core. CONSTITUTION: A power voltage supply controller for supplying power voltage with a semiconductor memory includes a controller(10), and a memory core unit(20). The controller produces the enable signal between high voltage and ground voltage by including a level shifting unit. The controller controls power supply by using enable signal. The controller includes an NMOS driver. The memory core unit applies the power supply voltage from the controller.
