SDRAM vs SRAM

Would an SRAM greatly outperform an SDRAM for the lpc4337?

Not looking at capacity but purely at the time required to read a fixed number of bytes from a 200 Mhz SDRAM and a 10ns SRAM.

Thanks

The synchronous bus used by the SDRAM is typically more efficient than the asynchronous bus used by SRAM. However, you have specified using a 10 ns SRAM which is very quick so it may be comparable. Also, SDRAM operation at 200 MHz is not supported on the LPC43xx (the maximum is 120 MHz).
