The register file always outputs two read data, i$.$e$.,$ Read data $1$ and Read data $2,$ and write to a register as identified by "Write register" in each cycle.

The data memory is where data are stored and accessed, while instructions are stored in different places $($i$.$e$.,$ the instruction memory$).$
