Semiconductor integrated circuit device |
摘要 |
A semiconductor integrated circuit device includes a main memory cell array, redundant memory cell array, write current source, a common node connected to the write current source, a first selector connected between the common node and one-side ends of main write wirings and a second selector connected between the common node and one-side ends of redundant write wirings. The redundant memory cell array is arranged in a position apart from the main memory cell array and the write current source is commonly used by the main memory cell array and redundant memory cell array via the common node.
