    Abstract: An address latch, a display device, and an address latching method are disclosed. The address latch includes a write control circuit, a write latch circuit, a latch control circuit, an intermediate latch circuit, and an output latch circuit. The write latch circuit is configured to latch an address data in response to N write control signals generated by the write control circuit, N data bits of the address data are divided into (M−1) data bit groups; the latch control circuit is configured to sequentially generate M latch control signals; the intermediate latch circuit is configured to, in response to first to (M−1)-th latch control signals, latch first to (M−1)-th data bit groups latched by the write latch circuit in a time-division manner; and the output latch circuit is configured to output the address data latched by the intermediate latch circuit in response to an M-th latch control signal.

    Abstract: A data caching circuit includes a ring signal counter, a switch, and a first latch. An output terminal of the ring signal counter is connected to a control terminal of the switch. An output terminal of the switch is connected to a control terminal of the first latch. The ring signal counter is configured to input a data transmission starting signal and a clock signal to generate and output a count control signal. A clock signal terminal of the switch is configured to input the clock signal, and the switch is configured to generate and output a data caching control signal according to the input count control signal and clock signal. A data signal input terminal of the first latch is configured to input a data signal. The first latch is configured to latch the data signal according to the data caching control signal input from the control terminal of the first latch. An output terminal of the first latch is configured to output the data signal.
