Memory works in simulation, but not on HW?

Well , it works on the rising edge of the clock, so its very simple, u just activate WR or OE for read or write , then put the address and at the first coming rising edge, data is either sampled for write , or output for read. I'm using normal microcontroller, and I even wait for multiple clocks before i sample the data. Like I said it is working fine in simulation. See the attachment of the simulation results.

Thx in advance man.
