Default data memory single cycle processor mips verilog code

library IEEE;
use IEEE.std_logic_1164.all;
use IEEE.std_logic_unsigned.all;
entity DataMEM is
port(datain,address: in std_logic_vector(31 downto 0);
CLK,wrtenb,readenb: in std_logic;
dataout: out std_logic_vector(31 downto 0));
end DataMEM;
architecture behav_DataMEM of DataMEM is
type MEM_type is array(1023 downto 0) of std_logic_vector (7 downto 0);
signal data_mem : MEM_type;
if (CLK' event and CLK='1' and wrtenb='1') then
data_mem(conv_integer(address)+3) <= datain(31 downto 24);
data_mem(conv_integer(address)+2) <= datain(23 downto 16);
data_mem(conv_integer(address)+1) <= datain(15 downto 8;
data_mem(conv_integer(address)) <= datain(7 downto 0);
end if;
if (readenb='1')then
dataout(31 downto 24) <= data_mem(conv_integer(address)+3);
dataout(23 downto 16) <= data_mem(conv_integer(address)+2);
dataout(15 downto 8<= data_mem(conv_integer(address)+1);
dataout(7 downto 0) <= data_mem(conv_integer(address));
end if;
end process;
end behav_DataMEM;

#anybody know how to write verilog code of data memory for single cycle processor ?i have the code in VHDL.i wan convert to verilog code,can help ?
