An internal processing capability is
added to a computer memory by adding a small processor, a small amount
of processor RAM memory, a small amount of non-volatile memory, and
some logic. During wafer testing the internal processor system allows
the memory to be tested at full speed and substantially simultaneously
with the testing of other memories on the wafer. At any stage after
packaging, the part can be tested by having the host processor read the
non-volatile memory, determine what test program to use, load it into
the RAM memory, and run the Self-Test program. The internal processor
system also allows additional functions such as data searching, data
moving, and graphics primitives to be performed entirely within the
memory.
