Connecting sram to cpu?

Hello, How can I connect the SRAM component to the cpu? [see my project here][1] I mean, the cpu has the "vcc-dram(0-11)" which I, I GUESS, should be connected to the right part of the SRAM component (D0 to D7); **But how do I select the address (left side: A0-A18)?** Should I add **many** logical ICs between the cpu and the sram to discriminate which Axx I want to activate? Could someone show me (without passive components in the way, just the logic)? Thanks [1]: https://easyeda.com/jpkursch/Sram_test-1f229ece18854914bf9b9c3247d9b338

Maybe I just cannot do it directly that way. I may need a SRAM controller which doesn't come with many cpu (dram controllers). I don't know. **What do you use in your project as far as ram type is concerned? **

Have you studied the datasheets and applications notes for your choice of processor for guidance and examples? Are there any reference designs available? Schematics of evaluation or development boards?

Actually the cpu supports external SD/MMC, NAND, SDRAM (ddr2,ddr3..) but no external SRAM is supported. So yeah.. it is a no go here. Thanks Andy
