Insufficient RAM for Flash Algorithms !

I clone the repository on GitHub, which is the accompanying code for the Application Note nAN-36 "Creating Bluetooth Low Energy Applications Using nRF51822", in the nrf51822/Board/pca10001/s110/ folder. Though I can successfully build the project, I can not download the image the the PCA10001 target board. The log is as shown below:

Insufficient RAM for Flash Algorithms ! Erase Failed! Error: Flash Download failed - "Cortex-M0"

===================================================================================

"Insufficient RAM for Flash Algorithms ! ?" what is that mean? How did it happen?

I did download the S110 SoftDevice using nRFgo Studio before downloading the application image within Keil μVision.

Thank you for your help.
