发明名称 Semiconducteur integrated circuit device allowing change of product specification and chip screening method therewith.
摘要 <p>A semiconductor integrated circuit device capable of changing the product specification. The semiconductor integrated circuit device comprises an integrated circuit section containing a first circuit section (7) having a first function and a second circuit section (31) having a second function, and active signal generator means (3) for producing an active signal for activating the first circuit section or the second circuit section. To change the product specification, the integrated circuit device further comprises receiving means (27) for taking in a decision signal for determining the product specification, switching signal generator means (29), connected to the receiving means (27), for producing a switching signal for changing the product specification based on the decision signal, and switching means (9) which receives the active signal and the switching signal, and which, based on the switching signal, changes the supply of the active signal to either the first circuit section (7) or to the second circuit section (31). &lt;IMAGE&gt;</p>
