    \item \textbf{Description} : Generates a RAM of \verb-regNumber- words of \verb-n- bits named \verb-modelname-.
    \item \textbf{Terminal Names} :
    \begin{itemize}
        \item \textbf{ck} : clock signal (input, 1 bit)
        \item \textbf{w} : write requested (input, 1 bit)
        \item \textbf{selram} : select the write bus (input, 1 bit)
        \item \textbf{ad} : the address (input, \verb-Y- bits)
        \item \textbf{datain} : write bus (input, \verb-n- bits)
        \item \textbf{dataout} : read bus (output, \verb-n- bits)
        \item \textbf{vdd} : power
        \item \textbf{vss} : ground
    \end{itemize}
    \item \textbf{Parameters} : Parameters are given in the map \verb-param-.
    \begin{itemize}
        \item \textbf{nbit} (mandatory) : Defines the size of the generator
        \item \textbf{nword} (mandatory) : Defines the size of the words
        \item \textbf{physical} (optional, default value : False) : In order to generate a layout
