FLASH MEMORY APPARATUS AND READ OPERATION CONTROL METHOD THEREFOR

摘要

PURPOSE: A flash memory apparatus and a read operation control method therefore are provided to improve operation speed by replacing a block where reading repeatedly occurs with a spare block. CONSTITUTION: A flash memory(10) comprises a plurality of blocks. A read operation control circuit(20) determines the replacement of a block according to the number of reading each block. The read operation control circuit comprises a map administration unit, a counter, and a comparison unit. The map administration unit generates and updates a counter map. The counter map stores the number of reading operation. The counter counts the number of reading the block. The comparison unit compares a read times with the number of maximum repetitions.
