RUSH CURRENT CONTROLLER AND RUSH CURRENT CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To attain stabilization of power supply by suppressing drop of a power supply voltage to be supplied to an LSI by enlarging a through-rate of a rush current from a DC constant voltage power source just after processing start in the LSI.;SOLUTION: In a rush current controller provided on a data processing means capable of holding processing data in response to a data hold signal HOLD1, just after processing start, the data hold signal HOLD1 is generated which has a plurality of data hold terms (HOLD1 in Fig.5(D) is H term) which vary step by step with the passage of time (ENABLE in Fig.5(B) is transient to H), and the generated data hold signal is outputted to the data processing means.;COPYRIGHT: (C)2008,JPO&INPIT
