NAND Flash Bad Block Schemes

Data IO Software Solution

NAND Flash Bad Block Schemes

Seamlessly manage NAND device complexities with the world's largest library of Bad Block Schemes.

Our team of global device support engineers are experts in the field of NAND device technology. We simplify NAND bad block management so you can focus on what you do best.   NAND Bad Block Management software suite includes several different bad block management schemes needed for loading data patterns into NAND devices.

  • Field Proven
  • Skip Block method is the default scheme
  • Runs under TLWIN
  • References device specs from the semiconductor manufacturers
  • General schemes (Reserved Block Area, Samsung GBBM...)
  • Also developed for unique customer applications

Data I/O’s NAND Flash Bad-Block Schemes software option is for engineers and systems designers implementing NAND Flash memories into their electronic products. New products increasingly use NAND Flash memories instead of NOR Flash memories due to the large cost advantage. While NOR memories are error-free, NAND memories require bad-blocks to be detected and managed while writing to the device. About two dozen methods are commonly used to manage bad-blocks today. The “Skip Bad-Blocks” scheme is included with TaskLink™. The NAND Flash Bad-Block Schemes software option package contains numerous new sophisticated schemes. Data I/O offers this software option to help designers more quickly implement products on NAND Flash memories with proven bad-block handling methods.
