DE1 Reading / Writing to SRAM

Hi, I'm trying to design a SRAM controller that can be used to read or write to or from the DE1's SRAM for a project and I have absolutely no clue where to begin. I've got the basic entity skeleton a...

So far I have the following code...

architecture structural of SRAM_16bit_512K is

begin

process(iCLK)

begin

SRAM_OE_N <= iREAD;

SRAM_WE_N <= iWRITE;

if ( iCLK'event and iCLK = '1' ) then

if ( iWRITE = '0' and iREAD = '1' ) then

SRAM_CE_N <= '0';

SRAM_ADDR <= iADDR;

SRAM_DQ <= iDATA;

elsif ( iWRITE = '1' and iREAD = '0' ) then

SRAM_CE_N <= '0';

SRAM_ADDR <= iADDR;

oDATA <= SRAM_DQ;

end if;

end if;

end process;

end structural;

is this correct? It seems to be reading and writing to and from the SRAM correctly but I'm not sure...
