Abstract

　半導体メモリ情報蓄積装置は、蓄積部（１）のブロックが使用中である場合は、使用中のブロックをusing-list （４１２）に登録し、未使用である場合は、書き込み回数が最大使用回数と同値であるブロックをfree-high list （４１３）に登録し、書き込み回数が最大使用回数未満であるブロックをfree-low list （４１４）に登録する。そして、free-low list （４１４）に登録されている未使用ブロックから書き込みブロックを選出し、素材データを書き込む。また、ブロックから素材データを消去するとき、そのブロックを書き込み回数と最高使用回数に基づいてfree-high list （４１３）又はfree-low list （４１４）に登録する。
