Automated error detection for multiple block memory array chip and correction thereof

摘要

A semiconductor memory device comprises a plurality of memory cell array blocks. An address changing system is provided in each memory cell array block. The same address signal is applied to these address changing systems. Each address changing system comprises a plurality of linking devices. By previously blowing out any of the linking devices in each address changing system, an externally applied address signal is changed with another address signal to be applied to a corresponding memory cell array block.
