10 / 26 page KM29U64000T, KM29U64000IT FLASH MEMORY 10 NAND Flash Technical Notes (Continued) Program Flow Chart Start SR. 6 = 1 ? Write 00H SR. 0 = 0 ? No * If ECC is used, this verification Write 80H Write Address Write Data Write 10H Write 70H Write Address Wait for tR Time Verify Data No Program Completed or R/B = 1 ? Program Error Yes No Yes * Program Error Yes : If program operation results in an error, map out the block including the page in error and copy the target data to another block. * operation is not needed. Error in write or read operation Over its life time, the additional invalid blocks may occur. Through the tight process control and intensive testing, Samsung mini- mizes the additional block failure rate, which is projected below 0.1% up until 1million program/erase cycles. Refer to the qualification report for the actual data.The following possible failure modes should be considered to implement a highly reliable system. Failure Mode Detection and Countermeasure sequence Write Erase Failure Status Read after Erase --> Block Replacement Program Failure Status Read after Program --> Block Replacement Read back ( Verify after Program) --> Block Replacement or ECC Correction Read Single Bit Failure Verify ECC -> Block Replacement or ECC Correction ECC : Error Correcting Code --> Hamming Code etc. Example) 1bit correction & 2bit detection |
