DATA ACCESSING INTERFACE HAVING MULTIPLEX OUTPUT MODULE AND SEQUENTIAL INPUT MODULE BETWEEN MEMORY AND SOURCE TO SAVE ROUTING SPACE AND POWER AND RELATED METHOD THEREOF
DATA ACCESSING INTERFACE HAVING MULTIPLEX OUTPUT MODULE AND SEQUENTIAL INPUT MODULE BETWEEN MEMORY AND SOURCE TO SAVE ROUTING SPACE AND POWER AND RELATED METHOD THEREOF
A data accessing interface between memory and source in LCD display IC includes a multiplex output module and a sequential input module. Suppose a row width of the memory is N bit. The multiplex output module is for outputting a row N-bit digital data. The multiplex output module includes a buffer for receiving the row N-bit digital data from the memory; and a multiplex unit for continuously selecting M bits from the N bit digital data to output to source. After N/M times, all of the row N bit digital data will be output to source. The sequential input module includes N latches and N/M latch control signals; when each latch control signal is active, it will latch M bit digital data from the multiplex output into M latches. After N/M latch control signals are active sequentially, the N bit digital data are stored into the N latches for source.
