how to write into sram

without using the $readmemb command ,can anyone suggesy how to read data from a rom to a ram...i want to realise this step in the hardware,not to read form a text file n load it...i want to write a code ,such that it depicts the exact manner in which ram's and rom's in our system communicate...how to do this?

model the memory block. then write RTL to generate addr, data, control lines to that memory.

You can structurally model the memory with a set of flip flops - that's the maximum extent of hardware representation you can do for the SRAMs because SRAM structures are fairly analog (with bit lines and sense amplifiers). Then use the enables of flops to allow the load value or use output enable to read out of the flops to represent memory function. Hope that clarifies
