Which type of volatile RAM has the least duration of data remanence when power-offed?

Hi:

Which type of volatile RAM has the least duration of data remanence
when the power is offed?


Thanks,

Core memory?

Email IBM and ask if you can get a PCI express interface for this.

No, that is the most, not the least.

Some TTL RAM chips wake up with the same pattern just about every
time no matter what they had in them at power off.  Many low power
CMOS ones are very bad about holding onto values.

There are RAMs made with a hardware clear on reset.

   Hell, IBM  (& everyone else) had problems with core on mini computers
& mainframes.

   Core is a form of non volitle memory.  It was replaced by floppy and
hard drives, which are being replaced by flash memory.

   The 1101 was a slow, cantankerous 256 byte solid state RAM designed
in the '70s

No, its 42.

   Only if it falls into the 'Everything else' category. :)

SN7489 probably qualifies.

(Or any other chip that holds irreplaceable information. 
But that's a different subject entirely :-)
