how to check the data in SRAM

Gupta,

If you have access to an oscilloscope or actual logic analyzer, I would also recommend looking at your address/data lines in the "analog" domain if you are operating at any kind of reasonably high speeds. I have run into signal integrity issues before due to poorly designed development boards. Was only running at 50MHz, but whenever several address lines would transition at the same time, the transient would affect some of the data lines as well, resulting in incorrect data.
