摘要
A comparator determines the fidelity of a response vector received from a memory under test. The comparator includes a first logic gate configured to output a first value that is the logical OR of a first proper subset of bits of the response vector. A second logic gate is configured to output a second value that is the logical NAND of the proper subset of bits. A first multiplexer is configured to select between the first and second values based on the value of a first bit of a check vector corresponding to the response vector.
