... for the logo - match?

It seems they are definitively out of business. I had an encounter with their chips (this is the case when I wrote a specific hardware test I referred to in the "testing" thread recently), but those were low-power 6264's and some of them were sclerotic. The test would store a certain pattern, then leave them alone for several seconds/minutes, read out and check, then write another pattern etc. The patterns were nothing particular, simply AAs and 55s, as it seems that there was no relationship between the data and the loss - they simply leaked from one state to the other (I don't remember if it was 1->0 or the other way round).

Just a note - this was not the only manufacturer who produced defective SRAMs, strangely enough all I have seen were of the "forgetting" type in some way or other, no shorts between adjacent address/data lines etc. The worst of them performed like a random generator... Since I fought with batches of this scrap, we stick to ZMDs, they are sound and stable in all possible situations.

However, I've seen a lot of what you are referring to in cheap 486 motherboards and as these are fast cache SRAMs and certainly experienced already some service, they will be most probably OK otherwise the board would be thrown out immediately. However, be warned, these cache chips suck power like crazy, like 100mA in idle, compared to say tens of uA for the 62xxx low power low speed ones.
