In accordance with one aspect of the invention, a system includes memory test input logic that acquires test data via a data port, a memory test enable logic and a memory test output logic. In accordance with another aspect of the invention, a method acquires test data via a data port, writes the test data to a memory address in the memory array, and reads output data from the memory address in the memory array. Then, the method compares the test data and the output data to determine if the memory address in the memory array passes a test.
