Semiconductor integrated circuit, BIST circuit, design program of BIST circuit, design device of BIST circuit and test method of memory

摘要

A semiconductor integrated circuit includes a memory, a BIST main circuit and a BIST sub circuit. The BIST sub circuit is to generate a row address pattern or a column address pattern of the memory and includes a boundary address generation circuit for alternately generating a top address and a bottom address of the memory for at least one of the row address pattern and the column address pattern. The BIST main circuit is provided in common with a plurality of memories and the BIST sub circuit is individually provided corresponding to the memories. The boundary address generation circuit includes a top address memory unit for storing the top address and a top/bottom address generation unit for reading out the top address and alternately outputting the top address and the bottom address.
