Hi,

   

We have a product using a 70ns SRAM low power version and recently has swithed to a 45nS second source(lower power consumtion then the orginal one). and the product started to have some strange failure, had spend some time checking on various parts and found the replacing the SRAM with the slower one fix the problem. We are using a 8051 type controller. What would be the problem, we looked at the bus signal and all seems to be clean.

The problem seems to be the setup time of the address line WRT the write strobe.
