摘要： A method for operating a non-volatile memory is provided. The non-volatile memory includes a plurality of physical blocks having a plurality of data blocks and spare blocks. An index is obtained by comparing an average erase count of selected physical blocks with a first threshold. Each erase count for each physical block is the total number of the erase operations performed thereon. A performance capability status for the memory is determined according to the index. The performance capability status is set to a first status when the average erase count exceeds the first threshold. An indication is generated based on the performance capability status. A limp function is performed in response to the first status for configuring a minimum number of the at least some spare blocks reserved and used for data update operations.

摘要： A data storage system comprises a host and a flash memory device having a non-non-volatile memory. A controller of the flash memory device calculates an average erase count of the flash memory to obtaining a remaining period of time indicating usable lifespan of the flash memory device. The host obtains an index by comparing the average erase count with a first threshold and determines a performance capability status for the flash memory device. The performance capability status is set to a first status when the average erase count exceeds the first threshold. The host generates an indication based on the performance capability status and performs a limp function responsive to the first status. The limp function loads a predetermined in-system programming code for replacing an original one to configure a minimum number of at least some spare blocks of the flash memory reserved and used for data update operations.
