REPAIRING CIRCUIT OF MEMORY

摘要

The circuit can repair any of the failure columns by gathering the Redundant columns in one block. The circuit comprises: block 0 (1), with the Redundant columns containing Y decoder (1-1) for repairing, Y decoder (1-2) and sense amplifier (1-3), for receiving word line signal from circuit part (A) which generate SAE. from block i to block n (1-N) containing Y decoder, sense amplifier and receiving signal SAEi, SAEn from circuit part (B).
