Abstract:
1. A program storage device readable by a machine, tangibly embodying a program of instructions executable by the machine to perform method claims for improving the efficiency of test sequences for testing an array of a plurality of random access memories (RAMs) embedded in logic, each of the RAMs having at least one read port and one write port, the read port having a plurality of output terminals and address input terminals and the write port having a plurality of data input terminals and address input terminals, the method steps comprising: a) applying an initial test sequence to a plurality of inputs of the logic; b) identifying which of the outputs of the at least one read port of each of the RAMs has an indeterminate value; and c) setting each of the outputs of the at least one read port in each of the RAMs having an indeterminate value to a known value by:
