Recently many different kinds of non-volatile memories have been proposed in order to replace the already existed SRAM-based memories. Despite the multiple advantages of those memories like low energy consumption, improvement of the area needed, nevertheless there also some drawbacks like longer write latencies and lower endurance. In this Master Thesis, different methods of architectural design of memory for embedded systems are proposed. The performance of two different kinds of memory, the already widely known SRAM and the emerging ReRAM is evaluated. We created two different implementations for each one of them, as data memory of an FFT application of an ASIP (Application Specific Instruction Processor). The first one is the simple implementation of each one of them and the second is the sub-banked scheme. Also architectural solutions are proposed in order to conceal in the most effective way, the long write latencies of ReRAM and the affection that they have in the performance of the whole system.
