Hi
 More back on subject, the MRAM looks like it is
a non-distructive read, unlike the core.

 Back on cores:
 
 It seems like they also used a 1/2 opposite
inhibit while doing reads to give them a little
more noise margine. This way, cores without a
x or y would have a 1/2 wrong way and those
with only x or y driven would have 1/2 positve.
The matching would get 2 - 1/2 or a full 1.5
write. Both X and Y would be driven with the
average Im, of all of the cores, and not half.
