Mac book error code meaning

I’m searching for the meaning of this code from MacBook Pro early 2011 model. I’m assuming it is a memory related code. Any help is appreciated.

Yes, it is a memory error. Your RAM may be bad or loose. Try reseating the RAM and see if that helps. If not remove one module and try running with the remaining one. Then do the same for the other module. It's a process of elimination.
