Managing data transfers in semiconductor devices by separating circuits for lower-speed-type data and higher-speed-type data

Abstract

Systems, methods, circuits, and devices for managing data transfers in semiconductor devices are provided. In one aspect, a method includes: selecting a first interface to receive higher-speed-type data at a first clock frequency; transferring the higher-speed-type data with a first speed along a first data path from the first interface through a first logic circuit to a driving circuit; outputting the higher-speed-type data by the driving circuit; selecting a second interface to receive lower-speed-type data at a second clock frequency that is same as the first clock frequency; transferring the lower-speed-type data with a second speed along a second data path from the second interface through a second logic circuit to the driving circuit, the first speed being higher than the second speed; and outputting the lower-speed-type data by the driving circuit.
