If you intend to use it as main core memory on an old CPU,
it will perform VERY poorly, as these memories need to erase
a page at a time, and the erase takes milliseconds. So,
writing ONE SINGLE word at a time would invoke an erase
cycle each time, slowing it to 1/1000 or worse the speed of
the original core memory. Also, most old CPUs have the
memory timing built into the CPU, and can't handle a memory
that says "wait".
