Please let me know the procedure for below
I am new for this design. I would like to know how to interface 4 SRAMs of 32 K bytes to 8051 microcotroller and I am developing code in C language in C51 Keil compiler.
Cy62256-SRAM 11.0592MHZ crystal
living in the past are you? 32k SRAMs will cost you way MORE than a 128k SRAM ($2 or so).

But, here requirement is by using 3x8 decoder to interface 4 SRAMS of 32K bytes with 8051. So,I am not able to exact Schematic also.
Requirements is to use 3x8 decoder. Why? Is it a school job?
no no, I am new to this field so, I am trying to interface like this way. so, just I said like this is my requirement
What Language are you writing the code with? A generic 8051 only supports 64K of RAM. So you will have to use another port pin to address 128K. The code will then have to insure the correct memory is selected. In this case a 3 to 8 decode will work. What is the part number of the chip you are using? Does it support 128K directly?
89c51 supports external 64k only by using one port pin I will interface another 64K
Thanks for giving information bye
