Zusammenfassung: | 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. |
