Getting data from SRAM(DE2-70)

Please help me~~!

I have two questions.

1. I would like to get get datasheet about SRAM(DE-70). But it's difficult to get it. would you tell me how to get it

2. I want to get data from SRAM(DE2-70) by oLEDR[15:0]

I store the number h'3210 in SRAM adress x200000

is this code valid to get data from address x200000

always(posedge iCLK_50)

if( oSRAM_A==32'h200000) <------SRAM first adress(x200000)

oLEDR <= (SRAM_DQ[15:0]);

...I uploaded my code.. please
