Abstract

A semiconductor device includes a mode register set suitable for generating a first internal control signal and a second internal control signal, a per-DRAM addressability (PDA) driving unit suitable for resetting the mode register set in response to the first internal control signal and an input value of data inputted through a data pad, and a cycle redundancy check (CRC) driving unit suitable for performing a CRC operation by checking whether or not data are correctly inputted through the data pad without an error in response to the first internal control signal and the second internal control signal.

First claim

What is claimed is:

1. A semiconductor device comprising:
a mode register set suitable for generating internal control signals including a first internal control signal and a second internal control signal;
a per-DRAM addressability (PDA) driving unit suitable for resetting the mode register set in response to the first internal control signal and an input value of data inputted through a data pad; and
a cycle redundancy check (CRC) driving unit suitable for performing a CRC o…
