From 0x2000000 to 0x20002000 is memory used by softdevice, so you can't use all 16 KB. Your application can use only 8 KB of RAM from 0x20002000. But to be sure try to update your SEGGER’s J-Link tools. Merry Christmas.

Dear Vladimir: Thanks very much! My computer is not use lite version of keil. my programm is 40KB. I think mem maybe out range. Our nRF 51822 shoulud be ARM Cortex-M0 low power 32-bit CPU running at 16 MHz. 256kByte on-chip Flash at 16kByte SRAM. But Version 4.6 Keil for my program show : [b]linking... Program Size: Code=10988 RO-data=252 RW-data=276 ZI-data=6756
FromELF: creating hex file... "._build\BTP_app_ection.axf" - 0 Error(s), 3 Warning(s). Load "C:\Keil\ARM\Device\Nordic\nrf51822\Board\pca10001\ble\BTP_app_ection V1.2-1223\arm\_build\BTP_app_ection.AXF"

JLink Info: Device "NRF51822" selected (256 KB flash, 8 KB RAM). Set JLink Project File to "C:\Keil\ARM\Device\Nordic\nrf51822\Board\pca10001\ble\BTP_app_ection V1.2-1223\arm\JLinkSettings.ini"
JLink Info: Device "NRF51822" selected (256 KB flash, 8 KB RAM).[/b] [i][/i]

Your settings seems to be correct for me. I have the same errors when my program is bigger then ROM size in settings. You have 0x2B00 - 172 KB ROM for your programm (this is maximum for nrf51822 with softdevice). I think this means what either your programm > 172 KB or maybe you use lite version of Keil, which is limited to 32 KB.

Try to verify and maybe increase memory size for target in project options: Options for Target -> Target.
