Abstract
A semiconductor device and a system may be provided. The semiconductor device may include a plurality of memory cell groups. An active operation may be performed in one or more of the plurality of memory cell groups in correspondence to a real active signal. A refresh operation may be performed in one or more of other memory cell groups in correspondence to a pseudo active signal.
Claims19
A semiconductor device comprising:
- a plurality of memory cell groups, and
- an active signal controller configured to, based on an active signal, generate a real active signal with respect to a memory cell group including an access target memory cell corresponding to an input address and generate a pseudo active signal with respect to one or more of other memory cell groups except for the memory cell group,
- wherein, while an active operation is performed in the memory cell group including the access target memory cell in correspondence to the real active signal, a refresh operation is performed in one or more of other memory cell groups in correspondence to the pseudo active signal.
