MEMORY SYSTEM PROTECTED FROM ERRORS DUE TO READ DISTURBANCE AND METHOD THEREOF

摘要

A memory system for preventing errors due to read disturbance and a method thereof are provided to suppress bit errors due to read disturbance when an operation of reading a particular page is performed repeatedly. A main page reading process is performed to read a main page of a flash memory(1). A reading number increasing process is performed to increase a reading number of the main page(2). The data of the block including the main page is copied to other block when the reading number is larger than the reference value(4). A reset process is performed to reset the reading number of the main page.
