Question

The random access memory is used for temporary storage of data and operating software. The memory is tested by performing walking bit and address circuits tests. Tests 1 through 84 are tests to verify the inputs for shorts, opens and current draw to protect the test equipment and the UUT. The data and address lines are checked to VCC (power) and to GND (ground). The address circuits (Test No. 85) test verifies the correct operation of the address lines and the address decoders on the UUT. The test consists of writing an address to each specific location. When this is done, each location in memory contains a unique address. After writing to the entire memory, then the entire memory is read for verification. This test detects any failures in the addressing circuitry, i.e. an address 1ine stuck in a state that results in locations having their storage bytes overwritten. The walking bit test (Test No. 86) verifies that the data 1ines function properly and without crosstalk. The walking bit test involves writing to the memory location, to be tested, a sixteen bit digital word which has a ZERO in every bit except the least significant bit which is ONE. This data field is then read from memory to ensure that no data bits have changed state. The ONE in the data field is memory and reading it back again. All memory locations are tested in this manner. The walking bit test is then repeated, as just described, except a ZERO is walked through a field of ONES. When the walking bit test has been completed, each memory will have been written to and read from 32 times.
