Summary:To provide a semiconductor storage device and a control method of semiconductor storage device capable of prolonging a life of the semiconductor storage device without complicated control.SOLUTION: A semiconductor storage device 1 according to one embodiment includes a bank A (11) and a bank B (12) which can operate complementarily to each other, and a bank selection circuit 14 for selecting one of the bank A (11) and the bank B (12). The bank selection circuit 14 alternately switches the banks to be selected each time an erase command instructing to erase data on either the bank A (11) or the bank B (12) is issued.SELECTED DRAWING: Figure 1 【課題】複雑な制御をすることなく半導体記憶装置の寿命を延ばすことである。【解決手段】一実施の形態にかかる半導体記憶装置１は、互いに相補的に動作可能なバンクＡ（１１）、バンクＢ（１２）と、バンクＡ（１１）およびバンクＢ（１２）のいずれか一方を選択するバンク選択回路１４と、を備える。バンク選択回路１４は、バンクＡ（１１）およびバンクＢ（１２）のいずれか一方のデータを消去すること指示する消去コマンドが発行される度に、選択するバンクを交互に切り替える。【選択図】図１
