Hi,
As you know that the LPC55xx has on-chip flash and on-chip RAM, both the on-chip Flash and RAM can be used to save application code and run from them directly. The LPC55S69 for example can run at 150mhz, but reading/executing code from flash requires delay clock, which can be set with the FLASHTIM bits in FMC configuration register. But If you run in on-chip SRAM, delay is not needed, so running in on-chip SRAM is faster than that of running in on-chip flash. user can copy code application code from flash to SRAM and execute in SRAM directly.
For the memory map, pls refer to Chapter 2: LPC55S6x/LPC55S2x/LPC552x Memory Map in UM11126.pdf
Hope it can help you
