Unlike the x36 and x18 versions of this device, the x8 and x9 versions do not give the user access to A0 and A1. SA0 is set to 0 at the
beginning of each access.
NW0 controls writes to DQ0:DQ3; NW1 controls writes to DQ4:DQ7
A2, A7, and B5 are reserved for future use as an address pin for higher density devices. They are not connected to the die on this device.
They may be left floating or be treated as an MCL pin (Must Connect Low) to assure the site will successfully accomodate a future, higher
density device. These pins may be marked as VSS, NC, or MCL by some vendors of compatible SRAMs.
