VHDL: RAM

RAM is a useful thing to have when you need to store bits of information for later, the code below is for a simple, single port write first, RAM module and test bench. This may seem like a great bit of code to have lying around, but in reality it’s more for educational purposes. If you were actually going to use a RAM module like the one below you should really use a RAM generator from the manufacture of what ever device you are using ie: Xilinx, Altera, Lattice… These generated module are designed to take advantage of special RAM blocks built into the FPGA which allows them to be fast and efficient.
