LDPC ECC (Low-Density Parity Check Error-Correcting Code) is an advanced technology utilized in NAND flash controllers to improve error correction capabilities, especially as the density of NAND flash memory increases. By integrating LDPC ECC functionality, controllers can correct more errors per page, which ultimately enhances the erase lifespan of 3D flash memory. This ensures better data reliability and longevity for SSDs utilizing 3D NAND technology.
