I recently bought a few MK4096-16 chips and wanted to test these. I could not (easily) find anything out there that did this, so for that reason I put together a Nucleo STM32F401 board, a ZIF socket and some batteries (with some adjustment diodes to get correct voltages).
The unit isn't completely working yet, timing is off here and there, but I hope to get it up and running (soon?). Anyway, I noticed that some of the MK4096 seems to have a few of their address lines stuck at LOW. That is, the STM32 can't drive them to 3.3 Volt (the 4096-16 should switch at 3.0 Volt). Only some of the chips have this, the rest seems fine.
Is this a particular normal way for a MK4096 to fail? Has anyone analyzed what failures that they usually experience? I am going to test for a number of things, adjacent flipped bits being one. Hopefully I can get 8 working ICs out of the 18 I bought...
