YeahDo you realise that that type of memory does not retain data when the power is removed ?

zzzzzzzzzzzzzzzzz..hi dm,
Sorry, I don't use Eagle, unable to open the file.

look who's here..heheheI never use DIP switches nor 18k pull up with SRAM because the SRAM would be controlled by an MCU.
What are you trying to accomplish?
You aren't.I believe I'm doing it right.
Yes It's incomplete..feeding data into the I/O pins made it look messy and I wanted people to understand. The lower 8 address lines to dip switch. I/O pins to other dip switchYour schematic is incomplete. I would expect to see how you are feeding data into the I/O pins for a write and how you are displaying the data for reading it. You don't show how you are de-bouncing the button to generate the write pulse. You don't show how you are driving the 8 low order address lines.
Here is your schematic exported as a .PNG file. (So that people that do not use Eagle can view it.)a

To do this. Click on file, select export as image, give it a file name with a .PMG extension.

lol...I was joking and I'm sure he knows thatComments like your last sentence are not likely to encourage people to help you.
