Semiconductor integrated circuit and method for controlling activation thereof |
摘要 |
To supply a ground potential Vss to a starter signal level shifter and a fuse information latch circuit on the basis of a fuse starter signal of which low level is shifted from the ground potential Vss to a negative voltage Vnn by the starter signal level shifter until the fuse information is latched to the fuse information latch circuit. After the foregoing fuse information is latched, a finally attained potential is supplied to the starter signal level shifter and the fuse information latch circuit. Therefore, it is possible to latch without shifting the low level, so that it becomes possible to easily shift the low level from the ground potential Vss to the negative voltage Vnn after latching.
