128 bytes for user RAM.
And 128 bytes for SFR's.
And 128 bytes for SFR's.

Because 2^7 (i.e. 2 power 7) = 128 bytes.

In 8051 Memory,
ROM (Program memory) - 4K (Internal memory) + 60K (External memory).
RAM (Data memory) - 128 bytes (Internal memory) + 64K (External memory).
ROM (Program memory) - 4K (Internal memory) + 60K (External memory).
RAM (Data memory) - 128 bytes (Internal memory) + 64K (External memory).
