Abstract
An input circuit includes a data input unit for the input of input data, a data latch for latching the input data, a reset unit for resetting the data latch, a clock synchronization unit for synchronizing the input of the input data to the data input unit, and a latch enhancement unit for blocking feedthrough current by functioning complementarily to the reset unit, and enhancing the latching operation of the data latch.
Claims19
