摘要： A data writing method for writing data to a flash memory includes writing an initial value to the data storage area, determining whether or not the writing of the initial value is performed normally based on a write flag, writing data to the data storage area when the writing is performed normally, and erasing a block including the data storage area when the writing is not performed normally. An initial value is written to the data storage area before writing data, so that whether or not an error correction code storage area contains the initial value may be confirmed. An erase operation of the block is performed only when the error correction code storage area does not contain the initial value, so that the number of times of erasure of the block may be reduced and the life of the product may be increased.
摘要翻译：一种将数据写入闪速存储器的数据写入方法包括将数据写入数据存储区域，根据写入标志确定是否正常执行初始值写入，当数据存储区域写入数据时将数据写入数据存储区域正常执行写入，并且当正常执行写入时，擦除包括数据存储区域的块。在写入数据之前将初始值写入数据存储区域，从而可以确认纠错码存储区域是否包含初始值。仅当纠错码存储区域不包含初始值时才执行块的擦除操作，从而可以减少块的擦除次数并且可以增加产品的寿命。
