Random access memory with redundancy relief circuit.

摘要

A redundancy repair circuit has a plurality of transistors in parallel controlled by address input gates and fuses to improve the switching voltage level of the operation for recharging the F1 from a condition wherein by transistors arranged by m number in parallel of the fuse portion in the redundancy circuit, the on resistance, the switching level may be controlled by the provision of the electric resistor or the transistor for resistance use in the common source.
