3.1.99 testRamMarch

Name

testRamMarch—assures addressability of memory, using a memory test block. Addressing
errors are sought by writing a pattern and its complement to each location. The test proceeds
as follows: (1) Starting at the beginning test address and proceeding towards the ending
address, each location is written with the starting pattern. (2) Starting at the beginning test
address and proceeding towards the ending address, each location is verified to contain the
starting pattern and is written with the complement of the starting pattern. (3) Starting at the
ending test address and decreasing to the starting test address, each location is verified to
contain the complement of the starting pattern and is then written with the starting pattern.

Note: testRamMarch only tests memory in blocks, thus specifying a memory area size that is
not a multiple of the block size results in part of the memory area being untested.
