Interfacing to a 32 bit data bus - Cypress.com Forums http://www.cypress.com/? Re: Interfacing to a 32 bit data bus http://www.cypress.com/?rID=42081
It is acceptable to use two 16 bit nvSRAM devices for memory width expansion by putting them side by side and accessing them together. The control signals (CS#, WE#, OE#) of one of the nvSRAMs should be tied to the control signals (CS#, WE#, OE#) of the other nvSRAM and connected to the controller's CS#, WE# and OE# lines respectively.

It is also recommended to pull up WE# line using a 5.6K ~ 10K pull up resistor.Pulling CS# and OE# lines is not necessary for the nvSRAM design although it is common design practice to pull control signals.
