Summary:To provide a semiconductor memory device employing PIM and an operating method thereof.SOLUTION: An operation method of an arithmetic unit included in the semiconductor memory device includes the steps of: receiving internal data stored in a memory bank group from memory bank groups per a first period; receiving external data that is stored outside of the memory bank group through an internal memory device per a second period shorter than the first period or is processed outside of the memory bank group; and performing a PIM calculation on the internal data and the external data per the second period.SELECTED DRAWING: Figure 1 【課題】 ＰＩＭを採用する半導体メモリ装置及びその動作方法を提供する。【解決手段】 半導体メモリ装置に含まれる演算器の動作方法は、第１周期ごとに、メモリバンクグループから、メモリバンクグループに保存された内部データを受信する段階、第１周期より短い第２周期ごとに、内部メモリバスを介して、メモリバンクグループの外部に保存されるか、あるいはメモリバンクグループの外部で処理される外部データを受信する段階、及び第２周期ごとに、内部データ及び外部データに対するＰＩＭ演算を行う段階を含む。【選択図】 図１
