DUAL PORT RAM CAPABLE OF INPUT/OUTPUT SIMULTANEOUSLY ON DUAL

摘要

a the latch unit operated by control signal, a first output buffer operated by a first read enable signal which is inputted from an input/output port of the first system, and which is connected to output of the latch unit; a second output buffer is connected to output of the latch unit and activated by the second read enable signal inputted from input/output port of second system; and the logic method which generates control signal with combination of the first and second write selecting signal. The output of the first output buffer is determined by the first read enable signal and the output of the second output buffer is determined by the second read enable signal
