Main System Memory
The PS3 has 256MB of 64 bit bus Rambus XDR main system memory. Some models use four 64MB Samsung chips, while other models uses four 64MB Elpida chips. Note that another 256MB of GDDR3 memory is located inside the RSX chip using four 64MB Samsung chips. The earlier models with hardware PS2 compatibility also contained an extra 32MB of RDRAM using two 16MB Samsung chips.
