I know that is not complete,but will this work ? I want to use internal rom for program, and one external ram for data storing, pluse two 8bit I/O ports.


In addition to what has already been said, your RAM IC is always "output" and can't be read from or written to. Tie /CS to ground, /WE to 8052's WR pin, and /OE to 8052's RD pin.
