Title: Semiconductor memory device
Inventor: SASAKI TOSHIO
IPC: G11C29/00
Filed: 1993-12-22
Abstract: PURPOSE:To improve the number of pieces of word line capable of saving a defect without increasing preliminary main word lines by subdividing normal/ preliminary both memory blocks and corresponding with an additional address bit. CONSTITUTION:The main word line 8 is selected by the address bits A7-12, and the word line 28 is selected by the address bits 0-6, and a normal memory block 50 is accessed. The memory block 50 and the preliminary memory block 52 are divided to four parts of subword group 26 corresponding to e.g. A5, 6 of either address bits. A preliminary decoder 20 stores the information of a defect cell, and when the addresses coincide with each other, the decoder 20 prohibits main word line selection operation, and selects the preliminary main word line 22. Since the normal subword group 26 is replaced by the subword group 26 of the preliminary memory array 34, even when defect addresses range over plural main word lines, only one preliminary main word line 22 saves up to four subword groups.
