SEMICONDUCTOR MEMORY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a semiconductor memory device capable of reducing an empty space and suppressing area loss.

SOLUTION: The semiconductor memory device is equipped with a memory cell array including a plurality of memory cell rows and at least one redundancy memory cell row, a redundancy rescue signal generation circuit for generating a redundancy rescue signal for showing an address of the defective memory cell row, and a row decoder for receiving a row address signal for indicating the memory cell row including the memory cell to be accessed and selecting the redundancy memory cell row in accordance with the redundancy rescue signal generated by the redundancy rescue signal generation circuit. The redundancy rescue signal generation circuit is arranged so that it faces the decoder across the memory array.
