Title: Memory device with redundancy
Inventor: SAITOU SHINJI
IPC: G11C29/00
Filed: 1982-01-19
Abstract: PURPOSE:To reduce the occupation area of a switching part for redundancy by blowing fuses of all memory cells connected to a word line having a faulty bit and also blowing fuses corresponding to prescribed bits of a decoder for an auxiliary memory. CONSTITUTION:When fuses of all memory cells of a main body memory 20 connected to word lines W1, W2... selectively through the 1st decoder circuit 24 corresponding to a faulty bit are blown, none of those cells generates an output during selection. On the other hand, when the fuse of a corresponding part of the 2nd decoder circuit 25 for the auxiliary memory 21 corresponding to the fault bit address is blown and the memory is selected by the circuit 25, specifying the same address as the faulty address facilitates switching from the memory 20 to the memory 21. This simple constitution reduces the occupation area of a switching part for redundancy.
