Design 326 of RAM, the structure shown in Figure 2. Which, adr as address pins, cs, wr, rd, respectively, for the chip select, write and read the pin, din_out to input or output pin. When cs = 0 and wr from low to high (rising) when, din input data is written on the instructions of the unit adr when cs = 0 and rd = 0 时, adr corresponding data element in the data line read dout out. Because when data is written on the rising edge wr, so you can use TEC-CA single pulse button on the platform as a wr.
