6502 instruction set timings
What is the maximum RAM for 6502?
In order to make up somewhat for the lack of registers, the 6502 includes a zero page addressing mode that uses one address byte in the instruction instead of the two needed to address the full 64 KB of memory.
This provides fast access to the first 256 bytes of RAM by using shorter instructions.The 6502 is an 8-bit processor with a 16-bit address bus.
It is therefore able to access 64 kilobytes (216 bytes).
Since each 16-bit address is comprised of two 8-bit bytes, memory can be viewed as 256 pages of 256 bytes each.
