METHOD FOR READING E-FUSE DATA IN FLASH MEMORY DEVICE

摘要

A method for reading e-fuse data is provided to obtain reliable E-Fuse data by using low level read voltage and increasing time for reading the E-Fuse data. A method for reading e-fuse data is comprised of steps: setting a read time of configuration data to be different from a read time for normal data; reading the configuration data, especially the configuration data includes information of DC trim, option, repair, and a bad block and a time for reading the configuration data is longer than that for reading the normal data.
