PROTECTION CIRCUIT OF FLASH MEMORY IN SYSTEM ON CHIP

摘要

PURPOSE: A system-on chip flash memory protection circuit is provided to protect the memory of system-on chip by enforcing to reset the system-on chip during the predetermined time at the point of power-up. CONSTITUTION: A load(100) is connected between an output terminal(T1) and the ground. A delay unit(200) delays the state voltage(Vs) applied to the load as long as the predetermined delay time. A delay detection unit(300) detects the point of time when the delay voltage(Vd) delayed by the delay unit is shifted to the high level.
