Initially, you may do better using the mega wizard to generate the ram, then you know for sure that a ram will be used. Infered ram has to match the correct behavioural template to be correctly inferred, otherwise logic will be inferred.

Dear Admin,
I have created a memory ( but without wizard) and read it as follows
PROCESS (clock)
variable i:integer range -1 to 31:=-1;
BEGIN
IF rising_edge(clock) THEN
i:=i+1;
q1 <= ram1(i); -- output ( ram is mif file of 32 element, each of 3 bits)
END IF;
END PROCESS;
ram1 is external file that I successfully read its data , each element read in one clock cycle.
However , I am trying to get the first three elements after they read to apply a mathematical equation to them in next clock cycle. when I tried to create registers to carry the values , I unintentionally read three element at the same time so the memory transferred to logic elements.
My question is , How can I store only three elements and add them and then I get another three to add while keep reading? I tried to postponed in this way but am not sure if its true
BEGIN
IF rising_edge(clock) THEN
i:=i+1;
reg1 <= ram1(i);
reg2<=reg1;
reg3<=reg2;
q1<=reg3;
