Synchronizing refresh control circuit for a plurality of slices and semiconductor apparatus using the same

摘要

A semiconductor apparatus with a plurality of slices electrically coupled through through electrodes. Any one slice of the plurality of slices may be configured to generate a refresh cycle signal in response to a refresh command, and transmit the refresh cycle signal to the other slices through the through electrodes. The other slices may be configured to perform refresh operations in synchronization with the refresh cycle signal.

1. A refresh control circuit comprising:
an oscillator configured to generate oscillation signals in response to slice type distinguishment signals; a control block coupled to the oscillator, and configured to output a refresh cycle signal in response to a refresh command and the oscillation signals, and generate a refresh start signal in response to a slice matching signal, slice identities (IDs) and the refresh cycle signal; and a comparison block configured to determine whether slice addresses provided from the exterior of the refresh control circuit and the slice IDs correspond to each other, and generate the slice matching signal.
