Witrynanandpagetest: relevant only for NAND flashes, tests NAND page writing and reading in different sizes and order; this test was originally developed for testing the OneNAND driver, so it might be a little OneNAND-oriented, but must work on any NAND flash. The kernel module version is called mtd_pagetest. NAND flash architecture was introduced by Toshiba in 1989. These memories are accessed much like block devices, such as hard disks. Each block consists of a number of pages. The pages are typically 512, error correcting code (ECC) checksum. Typical block sizes include: 32 pages of 512+16 bytes each for a … Zobacz więcej Flash memory is an electronic non-volatile computer memory storage medium that can be electrically erased and reprogrammed.
