Normally you can alter that from the php.ini file found in your public_html folder. The setting is named memory_limit.
I did not see a php.ini file in your account so I placed a default one there for you. The memory limit in that php.ini file is set to 512MB, so you should be all set.
I hope this answers your question. If you have any more questions or information specific to the issue please leave a comment below so we can further assist you.
