noun
expanded memory
Computing term referring to memory beyond the conventional limit, especially in older PC architectures (e.g., EMS).
このソフトは拡張メモリーを利用して動作する。

Same meaning; 拡張メモリ is a slightly shorter variant without the long vowel mark.
Compound of 拡張 (expansion) and メモリー (memory), a direct calque of the English computing term 'expanded memory'.
