flash read/write

Hello, I am trying to read/write the flash memory of my DE0 development board with the next VHDL code but I am unable to store nothing in the memory. Can anybody help me?

-- Quartus II VHDL Template

-- Single port RAM with single read/write address

library ieee;

use ieee.std_logic_1164.all;

entity flashdriver is

port

(

clk : in std_logic;

datain : in std_logic_vector(15 downto 0);

we : in std_logic;

ready : in std_logic;

q : inout std_logic_vector(15 downto 0);

dataout : out std_logic_vector(15 downto 0);

nce : out std_logic;

noe : out std_logic;

nbyte : out std_logic;

nrst : out std_logic;

nwe : out std_logic;

nwp : out std_logic

);

end entity;

architecture rtl of flashdriver is

type state_type is (iddle,reada,writea);

-- Register to hold the current state

signal state : state_type;

begin

process (clk)

begin

process(clk)

begin

if(rising_edge(clk)) then

if (we = '1') then

nce<='0';noe<='1';nwe<='0';

q <= datain;

else

nce<='0';noe<='0';nwe<='1';

dataout <= q;

end if;

end if;

end process;

nbyte<='1';

nrst<='1';

nwp<='1';

end rtl;
