Refer to UM10430 chapter 4, section 4.3 for booting from external sources like SDRAM

http://www.nxp.com/documents/user_manual/UM10430.pdf

To boot from SDRAM, for flash parts, set boot pin p2_7 low and ( set OTP bits BOOT_SRC or boot pins P2_9, P2_8, P1_2, or P1_1 based on Table 15).

Hi nesrine,
You can use debugger to load code in the SDRAM. For Keil you will need a debugger initialization file that will setup clock and initialize SDRAM interface.
