Why Does a Memory Bank Allow Only One Bank Access per Operation?

Q: Why Does a Memory Bank Allow Only One Bank Access per Operation?

In a typical SDRAM or DDR SDRAM , only one bank can be accessed in a single read or write. This design simplifies timing and reduces electrical load on the memory bus. Multiple chips in a bank are activated together to match the bus width . Accessing multiple banks simultaneously would require complex coordination and increase latency.
