Abstract
A semiconductor device has a plurality of internal circuits capable of having two conditions of an active state and a precharge state in the internal circuits. The device comprises signal generation element for generating a first signal which causes said internal circuits to be initialized until satisfying a predetermined condition from a time when the power is supplied; and state set element which is connected to an external apparatus through an interface which is supplied an external state signal, and for setting a precharge state of the internal circuits by outputting an internal state signal corresponding to the external state signal in response to a supply of the first signal from the signal generation element.
Claims6
A semiconductor device having a plurality of internal circuits capable of having two conditions of an active state and a precharge state in the internal circuits:
- comprising
- timer signal generation means for generating a timer signal which causes said plurality internal circuits to be initialized until satisfying a predetermined condition after a predetermined time passes from a time when a power is supplied;
- and
- state set means interconnecting said timer signal generation means and said plurality of internal circuits and which is also connected to an external apparatus through an interface which is supplied by an external state signal, and for outputting an internal state signal corresponding to said external state signal in response to a supply of said timer signal from said signal generation means, thereby setting an operation state for said plurality of internal circuits.
