ABSTRACT:
A processor chip having a cache hit logic for determining whether data required by a processor is stored in a cache memory includes a dummy cell string that operates the same as a sense amplifier for sensing a tag address stored in a tag memory cell array and a comparison logic for determining whether the sensed tag address coincides with an input tag address, a dummy sense amplifier, and a dummy comparison logic. The processor chip having the cache hit logic improves the reliability of a hit signal and operation speed is not limited.
