1.Register file construction Creating read ports
2.Creating write port
3.Main Memory Address Processor MEMORY write Data in Data out read Memory ROM (Read only memory) RAM (Random Access Memory) SRAM (cache memory) DRAM (Main memory)
4.Typical sizes of SRAM are (32 or 64 or 128 or 256) x (1 or 2 or 4 or 8 bits) address chip select SRAM output enable data out 32K x 8 bits write enable data in How many lines are there in address, data in and data out?
