Web8 de ago. de 2024 · Parallel NOR Flash Interface. As the name indicates, parallel NOR Flash is interfaced to a memory controller using a parallel address and data bus similar to SRAM. Parallel NOR Flash devices available in the market generally support an 8-bit or 16-bit data bus. The width of the address bus depends on the Flash capacity.
