Can I switch SRAM from another brand w/ Renesas’ SRAM w/o changing PCB?

Latest Updated:03/16/2012

Question:

Can I replace SRAM from a different manufacturer with Renesas’ SRAM without having to change the PCB, even if the address pin number of SRAM of Renesas and the other manufacturer differ?

Answer:

Each manufacturer can number their address pins arbitrarily.
As SRAM function is full random access memory, users don’t have tocare about a pin's numbering, such as A0 or A1. Because users assign one address and select one memory cell, users can write/read data onthe assigned address and corresponding memory cell. So even if the address pin name is different, the device will work properly.
