[SOLVED] Problem with MSB LSB on SRAM

[Stavros84]

Hello
I want to use the SRAM IDT7130SA (1K X 8 DUAL-PORT STATIC SRAM) but i can't find out which one is the LSB and which one is the MSB to the Address and to Input/Output.
I want to use the left side of the SRAM. I read the manual but i don't understand.

I believe that it should be like this:
A0L->LSB
.
.
A9L->MSB
and
I/O 0L->LSB
.
.
I/O 7L->MSB


I think this is wrong.
Does anyone know which are the right?

The general rule of thumb is that the higher numbered address bit is the MSB. The data can be any way you like it, since you control its format.
