Title:
SEMI-CUSTOM SEMICONDUCTOR INTEGRATED CIRCUIT
Document Type and Number:
Japanese Patent JPH10241397
Kind Code:
A
Abstract:

To improve yield of a semiconductor integrated circuit including an on-chip-memory designed by a design technique of a compiled memory.

A redundant memory 10 and the like are arranged in an empty region of a semiconductor substrate 1 to which a memory 5 designed with a compiled memory type in which a layout shape is decided conforming to the number of respective bits allotted to a row address signal and a column address signal, a CPU 3 accessing this memory 5, and the like are mounted, a defective part of the memory 5 is replaced by a redundant memory 10. Thereby, yield of a semi-custom semiconductor integrated circuit can be improved without mounting constitution forcedly for relieving redundancy to the memory 5 designed by a complied memory technique.
