DRIVER CIRCUIT OF PSEUDO SRAM, IN WHICH INSUFFICIENT VOLTAGE SUFFICIENTLY IS SUPPLIED

摘要

PURPOSE: A driver circuit of a pseudo SRAM is provided to maintain data by supplying an insufficient voltage sufficiently when having a core voltage lower than a driving voltage. CONSTITUTION: A comparator(300) controls a switching unit(310) by outputting a high signal and a low signal selectively by comparing an external voltage with a core voltage. The switching unit outputs a boosting voltage and the core voltage by opening/closing the switch according to a control signal being output from the comparator. And a driver unit(320) is connected to the switching unit and is driven according to the first driving voltage and the second driving voltage.
