The information you posted lists your MBP having 4 GB of memory (RAM - Random Access Memory) and you can go up to 8 GB of 204-pin DDR3 SO-DIMM RAM.

Upgrading RAM in MacBooks and MacBook Pros​

But if you meant "storage capacity" with memory *, you can get any 2.5" S-ATA HDD or SSD with a maximum height of 12.5 mm and expand your storage capacity to 1.5 TB via HDD or 512 GB via SSD.

MacBook, MacBook Pro: Replacing the Hard Disk Drive, transferring data to the new HDD

the guide includes:

• 0. Identify your MacBook or MacBook Pro
• 1. Getting a new HDD
• 2. Guides to replace the internal HDD with a newer one
• 3. Transferring data from the old HDD to the new HDD
• 4. Using the optical disk drive (ODD) slot for placing an SSD or HDD inside the MB/P (OPTIBAY)

​

* Btw, "memory" is not the same as "hard drive / storage capacity":

• Computer Storage: Ram vs. Hard Drive Space
• RAM vs. Hard Disk

It is recommended, to have 10 to 20 % of the SSD/HDD's capacity unused.
The above links also apply to SSDs.
