Testing of memories that decode a serial stream of address data to access the memory may be performed by cither successively halving the number of selected word lines as each address bit is acquired, until a single word line is selected, or by rotating the selection bits in its shift register to select a new set of address lines. As such, a combination of incomplete addressing and rotation can efficiently test large memories by reading and/or writing groups of words. Similar techniques may also be applied to non-memory devices. |
